As each day of the 2026 NBA offseason passes, we inch closer to the start of the 2026-27 regular season for the Boston Celtics. And as Opening Night draws nearer, the outline of the roster that will take the floor for Game 1 of 82 is starting to come into focus as well.
After Celtics President of Basketball Operations Brad Stevens traded star forward Jaylen Brown to the Philadelphia 76ers, it became clear that this is a critical season for the team's current contention arc, with the team being remade to maximize the rest of the team's sole superstar, Jayson Tatum. What is the ceiling, floor, and our expectation for each of the players currently under contract with Boston given this sea change in structure for the team?
To such an end, Daniel Donabedian
and Justin Quinn of the Celtics Wire took a player-by-player deep dive into the answers for these questions. So let's dive into our assessment for Chris Cenac Jr. for this edition of our player projections for the campaign soon to arrive.
Chris Cenac Jr. - center/forward
Ceiling
JQ: On one hand, Cenac Jr. was seen as a top recruit before a college career at Houston had the Louisiana native playing in a very specific role and in a play style that did not compliment some of his most important big man skills, so he could easily exceed expectations. But on the other, it wasn't just his usage and fit that saw Cenac slip to Boston's range of the 2026 NBA Draft.
So for me, this tells me a reasonable ceiling for the Celtics rookie center is forcing his way into the regular rotation as a real contributor able to protect the rim and hit occasional, mostly open shots from 3-point range. And if it were not for the glut of bigs Boston has on the team right now, I'd even go as far as to say he might have the run to get there. But he will have to earn it to get (and stay) on the court, which makes this outcome a bit unlikely.
DD: Cenac Jr. may have been a late first-round pick in the 2026 NBA Draft, but it’s worth emphasizing that he was a consensus five-star recruit who was once ranked among some of the biggest names (including No. 1 overall pick AJ Dybantsa) of the upcoming rookie class. So, it’s not unreasonable to think the one-and-done Houston Cougar has a high ceiling.
At 6-foot-11, Cenac Jr. can crash the boards well and he showed his shooting prospects during Summer League in Las Vegas. The 19-year-old should help the Celtics extend some offensive possessions, and a best-case scenario for next season would involve him getting more run in the NBA than the G League.
Floor
JQ: As we noted above, there are several players looking to get on the court this season ahead of Cenac in terms of seniority and skill both. Neemias Queta, Mitchell Robinson, Luka Garza, and Amari Williams at the 5, and Jayson Tatum, Paul George, Jordan Walsh, and Sam Hauser in line to log minutes as a power forward as well.
Cenac's likely floor, then, is simply not doing enough at the NBA level to earn real minutes with the Celtics. If he struggled at the G League level, he might not see the floor with Boston save for garbage time run. He'll have another season or two to put it together even in such a scenario as a young rookie, but this outcome is more realistic than his ceiling simply due to the roster makeup.
DD: Since Cenac Jr. is a rookie with unknown potential, the C’s may struggle to figure out what to do with him. Do they make him a center at times? Do they play him strictly as a power forward? The New Orleans native should be ready for anything, but a lack of a constant role could complicate his development.
If that happens, or if the C’s don’t have real room for Cenac Jr. on the roster, he may have a hard time getting consistent minutes. This isn’t a foreign concept for rookies, especially with the Celtics, yet it’s difficult to predict how a young player will handle that. At worst, this dilemma takes Cenac Jr. down a path similar to first-round picks of Celtics past like Romeo Langford or Aaron Nesmith (although, things ultimately worked out for Nesmith with the Indiana Pacers).
Expectation
JQ: I suspect Cenac's rim protection and rebounding will bee enough to earn him a minor role based on matchups that grows some on nights where Mitchell Robinson and Paul George sit. And given the recent history of both of those vets, I don't think it too much of a hot take to suggest this is a reasonable expectation for his first season with Boston.
Taking advantage of those opportunities within the game he already has at his disposal will be critical, however, to such an outcome. Boards and blocks should make him a helpful option for coach Joe Mazzulla, but if he tries to do too much too fast in Boston's complex play style, he might play himself right back onto the bench.
DD: Being a rookie and all, Cenac Jr. is hard to get a read on right now. His positional flexibility could help him or muddle his role. Regardless, I think he’ll be able to enter at least a dozen regular-season games with the Celtics and learn from stars like Jayson Tatum and Paul George.
Plus, Boston’s player development staff is one of the best in the business, making me confident that Cenac Jr. will up his shooting numbers and eventually shed his label as a potential project player. When these things happen remains to be seen — it could take a season or two or maybe longer. If the Celtics can wait it out (and avoid a possible expansion draft steal), I can picture Cenac Jr. becoming a productive NBA player with fairly high upside.
