How Does Jayson Tatum Fit on the Current Celtics?




They say you should never draft for fit, especially in the lottery. However, it is important for team’s rookies to have a place to fit in and play wherever they get drafted to. So today, we will be looking at Jayson Tatum and evaluating how well he fits in regards to the Celtics' current roster.

The hope is that Jayson Tatum brings fills one of two big holes that this Celtic team has had for years, getting a bucket when nothing else works (the other hole being rebounding). The Celtics are full of guys who can score, but really Isaiah Thomas is the only one who can be depended on to create a shot reliably for himself. Jayson Tatum has the skills and the tools to be an excellent isolation scorer due to his shooting, ball handling, and length.

Scoring

Tatum is one of the best isolation scorers in this draft. He averaged 1.047 points per possession in isolation plays this season, placing him in the 86th percentile of all college players. He’s not your traditional isolation scorer though. A lot of his damage is done in the post where he deploys a wide arsenal of moves coupled with excellent footwork to punish defenders. In the post, he averaged 1.087 points per possession, putting him in the 94th percentile of college players. This man knows what this game is about. Here is a great example of his ability in the post. The defender knows he can go either direction to score on him. Tatum uses that knowledge to his advantage using a quick spin fake into a fall-away jumper that is impossible to block.

Tatum employs similar moves in the post and on the perimeter. He loves jab steps, rip throughs, and pull up jumpers, oftentimes using all these on one play. His length and high release point makes it tough for smaller defenders to contest his jumpshot, while his dribble moves allow him to keep bigs on their heels.

This is exactly what the Celtics need on the wing. Avery Bradley is slowly becoming more of a scorer, but 35% of his shots are still of the catch and shoot variety. Gerald Green was probably the only wing the Celtics had last year that would consistently look to create his own shot. The Celtics were 2nd in assists per game last year, despite having a shoot first point guard. This is due to the Brad Stevens ball movement offense, but a lack of playmakers also forces the team to play that way. That is by no means a bad thing by the way. Ball movement and floor spacing are key in the modern NBA, but so is being able to score even when good defense is played. When everything breaks down, the Celtics need another option to score. Jayson Tatum could be that guy.

Rebounding

The Celtics have a problem rebounding. Everyone knows this. I am not going to spend too much time on their problem as a team. While he’s not the answer to all of the Celtics’ woes, Tatum is a superb rebounder for his position and I believe that will translate to the pros. He averaged 7.3 boards per game in college. His length and positioning are what gets him most of these. He is not an exceptional athlete, nor incredibly strong. But he has good size and long arms and he knows where to put himself to grab a good number of rebounds.

Tatum played mostly power forward at Duke and I would not be surprised to see him get most of his minutes at the 4 spot in the NBA as well, due to the high number of wings Boston is looking likely to have. The Celtics sorely need some bigs who can rebound, as Avery Bradley cannot continue to be one of the team’s top rebounders. If Tatum can bulk up some more, he should be able to fill this hole nicely for the Celtics. This could lead to a team that already plays fast to play even faster. Against teams with good rebounding bigs, the Celtics would often send four or five players to the defensive glass to ensure a rebound. This makes fast breaks much less common. However, if they could get away with just sending Tatum and whoever is playing center, that would allow the guards to get out and run more.

Defense

Jaylen Brown proved last year that in order to stay on the court for Brad Stevens, you have to play defense. Many games, Brown would make back to back plays on offense, maybe dunk over a dude and then hit a corner three, only to get pulled the next dead ball because he let his man go backdoor for an easy layup. Tatum may be able to come in and make a contribution on offense, but he will not stay on the floor unless he plays at least passable defense. Luckily for the Celtics, it looks like he has the tools to do that.

Tatum’s size should allow him to guard 3s and 4s, especially since he will mainly be playing against opposing backups. He used this size in college to rack up over a steal and block each per game. He definitely has the instincts to play good defense in the NBA. However, he kind of reminds me of Lonzo Ball defensively. They both have the size and ability to be good defenders, but they both need to work on their technique to keep ball-handlers in front of them and to rotate effectively.

Bigger power forwards with strong post games will definitely give him trouble out of the gate. He is long enough to guard the position, but at only 210 pounds, he is susceptible to getting bullied. Fortunately, the Celtics are one the best teams in the league at playing team defense (they have to overcome Isaiah Thomas’ defense). Look for Tatum to have help available when he needs it.

Playing with the bench means he will probably see most of his minutes with Marcus Smart, Terry Rozier, and Jaylen Brown (if they are all still on the team). All three of these are very disruptive defenders that should overcome any shortcomings on Tatum’s part.

Fit Concerns

There seems to be a theme in the top-3 of this draft class. No one is good at defense. Tatum is probably the best suited to fit in despite that, thanks to all the plus defenders the Celtics already have. Still, look for him to have trouble getting consistent minutes if his defense struggles in the early part of the season.

Offensively, Tatum is sometimes a willing passer. It’s almost as if he decides which possessions he’s going to shoot on and which ones he will pass the ball ahead of time. If he has ball-stopping tendencies that aren’t by design or occur late in the shot clock, the Celtics offense will struggle. The bread and butter of this team is moving the ball and passing up good shots to get great shots. I’ve seen nothing to suggest that Tatum will play selfish basketball as a rookie, but he needs to buy into the system and trust that he will still be able to get his points while working inside of it.

From day one, Tatum will probably have a small role off the bench (barring any huge acquisitions). He won’t be depended on to score, but that will be what he is on the court to do. If he plays well and proves to be not a liability on defense, look for his minutes to increase steadily throughout the year. If the Celtics add one or both of Gordon Hayward or Paul George, he probably will not have much of a role at all, depending on how the roster shakes out after that. Unfortunately for him, he plays the same position as both of those guys and he would also be competing with Jaylen Brown for minutes on the wing. This is not an ideal fit, position wise (I think the Celtics would have loved someone who is bigger and plays the 4 and 5) but Tatum will most likely carve out a role for himself and the Celtics will make it work.

Conclusion

Tatum has the potential to fill a need for the Celtics with his scoring ability. He will need to earn his minutes by doing the little things like rebounding and defending. If he buys into team basketball and Stevens’ system, he should be able to contribute from the get-go. He could be seeing limited minutes due to the vast number of wings that could potentially be on the Celtics roster.

Celtics Player Development Part 2: The Bench

Image result for marcus smart jaylen brown


Last week, I looked into how the Celtics’ starters developed throughout the year. Now it’s time for the bench. The development of this Celtics bench may be more important than that of the starters due to the substantial number of young players on it. Jaylen Brown and Marcus Smart look like they will be core pieces of the Celtics future, Terry Rozier seems like he could be in the long-term plans, and if Kelly Olynyk is back next year, he will be a piece for the future too. Basically, the future of this Celtics team will depend on the development of these current bench guys, as well as the next couple of draft picks (thanks Brooklyn).

A common theme amongst the starters was what I like to call the “Al Horford Bump” when it comes to their shooting efficiencies. The theory is that playing with Horford opens everyone else up for more open shots, allowing them to shoot higher percentages. Smart saw a small increase across the board for his percentages, however they are still abysmal. Once this team becomes a serious contender, Smart needs to either be shooting a lot better than 35.9% from the floor, or not take nearly 10 shots a game. The improvements Smart made aren’t even enough to call them promising, but he at least is trending in the right direction. I would upgrade his shooting grade from an F- last year, to just your regular old F this year.

Thankfully for Marcus, shooting is not the most important aspect of his game. Elite defense and hustle keeps him on the floor. Smart saw a small increase in steals and blocks that are in line with his increase in minutes. Despite playing three more minutes per game, his rebounding number actually decreased this season. He still pulled in a respectable-for-a-guard 3.9 per game, but Smart’s body and skillset should allow him to be an elite rebounding guard, I would hope that improves in the future. What was probably Smart’s biggest development was his playmaking. He increased his assists by over 50% which is huge for this Celtic team. The Celtics sorely needed a secondary playmaker for when Isaiah sat or even when he was on the court, but playing off-ball. Al Horford and Marcus Smart combined to alleviate that need this year. If Marcus can continue to improve his ball handling while limiting his turnovers, he could be a very good pure point guard in this league. He probably will never be a high scorer, but don’t be surprised if he is an eight-assists-per-game player if he ever is a starting point guard running an offense.

Scary Terry has had to fight for every minute he has gotten so far in his career. After contributing really solid minutes in the playoff series against the Hawks last year, Rozier came into the year with Brad Stevens having some confidence in him, and his minutes reflected that. Terry’s game bares resemblance with Marcus Smart’s in that they are both poor shooters, but they still both play significant minutes. Terry’s specialty is his hustle, rebounding, and playmaking ability. While the limited minutes don’t lead to very impressive stats, having 3 rebounds in 17 minutes is darn good rate. Terry didn’t rack up many steals or blocks, but he was still an impactful defender due to his length, athleticism, and quickness, which made the Smart-Rozier backcourt a nice change of pace to a backcourt with Isaiah Thomas in it.

Overall, most of the increases in Terry’s stats can be explained by his increase in minutes. His minutes doubled, so his rebounds, assists, steals, and blocks all roughly doubled. That is still very good though. Oftentimes, players are effective in limited minutes but not able to translate that when they play more. The notable improvements came in his scoring, and the lack of increased turnovers. Terry, though still not very efficient, was much more efficient than last year. He shot about 9% better on threes as well as from the floor. This explains his increase in scoring. The lack of turnovers can be explained by the work he put into his handles. Rozier noticeably improved in this area, he looked much more comfortable dribbling with pressure, and was making smarter passes. His ball security grade went from a C- to a C+ this year. There is still room for improvement, but Terry made a big stride this year, so look for that to continue.

Since Jaylen doesn’t have another year in the pros to compare to, I figured we should look at his splits from before and after the all-star break. There are a couple of stereotypes about rookie seasons in the NBA. One is the “rookie wall” where rookies slow down and stop producing, either because they are fatigued from the longer season or because defenses have adjusted to their playstyle. Another is a “rookie surge” where they will improve after the All-Star break because they have finally adjusted to the NBA pace and style of play. Jaylen was definitely a surger. Jaylen improved in every single statistical category other than free throws and turnovers. And he didn’t just improve a little, he made a significant jump. His three-point percentage was probably the best thing to come out of his improvement. Coming into the league, the biggest question mark about Jaylen was his jump shot. It showed early on in the season. He clearly did not have the green light from three and he only shot 30% from behind the line. He must have figured something out over the All-Star break, because he started taking and making more, with his 37.9% mark being well above league average.

The increase in turnovers isn’t very concerning, as the increase is in line with his increase in minutes. I would like to see Jaylen improve his handle this offseason however, as that would bring his turnovers down to a rate that is very good. The only concerning metric from after the All-Star break is the free throw percentage. As we saw in Summer League, Jaylen is at his best when he is attacking the hoop and drawing fouls. However, when his minutes increased, his free throw attempts went down and his percentage dropped dramatically. Now, the drop in attempts and percentage could be tied to fatigue from playing three times the number of games compared to a college season or just from his increase in minutes. If that’s the case, it wouldn’t be terribly concerning, because many rookies need to adjust their conditioning to keep up with an 82 game schedule.

Jaylen Brown should become a very good scorer in this league. Maybe not a first option, but he should be a great second or third in the future. Going forward, I would like to see him increase his hustle stats. With his size and athleticism, he should be grabbing more than 3.4 rebounds. His steals and blocks need to increase as well, as he has the quickness and length to be a pesky defender, and I’m sure Brad will get that out of him.

Kelly’s role in the offense decreased a little this season with the signing of Al Horford. He still played the same minutes, but he took less shots. The major improvement from Kelly was his shooting from the floor. Shooting over 50% is great, especially for a rangy big man like Kelly. Kelly implemented a super effective pump fake into his game this year that has allowed him to get cleaner looks around the basket. This is huge for Kelly’s development, because up until this season, he was really a one-trick pony offensively. He could shoot the three and occasionally put the ball on the floor to attack the hoop. This year he improved his attacking and his post scoring. Adding things like these to his game will allow Kelly to stick around in this league for a long time. His inside scoring grade improved from a C to a B- this year.

It was nice to see Kelly’s rebounds and assists number increase. Playing with Horford should give Kelly opportunity to develop his passing and learn from one of the best passing bigs in the game. With his ability to stretch the floor, attack slower defenders off the dribble, and see the whole court with his height, Kelly has potential to be a dangerous distributor.

That’s about where the positive improvements end. His three-point percentage decreased, his free throw percentage did too, as well as his steals, blocks, and points, and his turnovers increased. I’m honestly not sure what to make of this. He played the same amount of minutes in a very similar role to what he did in the year prior. Maybe the pressure of playing for a new contract got to him? (Luckily for Kelly he had that awesome game 7 against the Wizards). I would love to have Kelly back on this team next year. I think he has some positive regression in him. However, he might cost too much for us to bring him back, especially if we are bringing in a max free agent like Blake Griffin or Gordon Hayward.

Overall, this bench improved this year. That was to be expected though as the majority of the bench is still on their rookie contracts. Player development of these guys in particular will be key going forward however. They all have significant improvements that they need to make if they ever want to be starting options in this league. I’m sure Brad and the rest of the staff knows this, so look for the young guys to make another big leap next year.
