A rumor about Boston Celtics center Amari Williams has been making the rounds, and it’s a big one: the 2025 second-round pick is said to have grown from a listed 6-foot-11 to 7-foot-2.
If that turns out to be true, it would obviously change the conversation around him. You can’t coach that kind of size, and Williams is already headed to Las Vegas for NBA Summer League as he works to keep building his case as an NBA-caliber player.
There’s still a long road to meaningful minutes in Boston. The Celtics have Neemias Queta, and they signed Mitchell Robinson, so Williams may not be a major factor in the 2026-27 season. Even so, a real jump in height would make his long-term upside a lot more interesting.
The catch is that the 7-foot-2 claim is still murky.
The latest version of the story comes from Heavy, which points to unspecified “reports” and says:
"According to reports, Williams has grown from roughly 6-foot-11 to around 7-foot-2 over the past year. Team staffers noticed him towering over teammates in practice and were astonished when they confirmed the growth spurt."
A search on X, formerly Twitter, shows fans were already asking about Williams’ size earlier in the offseason, but it doesn’t clearly show where the rumor started.
For now, there’s no clear, definitive sign that he’s actually 7-foot-2.
The most recent official listing comes from the Celtics’ Summer League roster, released earlier in July, which has Williams at 7-feet even. That’s still up from his college listing, and he already brought a 7-foot-5 wingspan to the table.
So unless something more concrete emerges, Williams looks like a 7-footer for now - just not necessarily a 7-foot-2 one.

Jayson Tatum Had A Telling First Reaction To Celtics Trading Jaylen Brown
Jayson Tatums first public reaction to the Celtics moving on from Jaylen Brown said plenty about how deep that partnership ran. After nine seasons together, the two had become the defining wings of Bostons core, so even for a franchise that has spent years chasing a title, a change that big was always going to land as something more personal than transactional.
The Celtics are betting that the roster flexibility and future draft assets they picked up will help them stay in the mix, but the human side of the move is harder to ignore. Browns departure leaves Boston with a very different look, and Tatums comments made clear that however the front office frames the deal, the adjustment around the locker room is going to take some time.

Celtics Fans May Want To Watch This Summer League Guard Closely
Day Day Thomas has a chance to make a quick impression in Bostons Summer League run in Las Vegas, and he arrives with a profile the Celtics always seem to appreciate. The guard came through Kilgore College before spending three seasons at Cincinnati, where he steadily carved out a role and showed he could help in more than one way.
What makes Thomas worth a closer look is the blend of defensive activity and perimeter touch that has followed him into this opportunity. He was known at Cincinnati as a disruptive defender who could also stretch the floor, and after a clear jump in his three-point shooting there, he now gets a chance to show that skill set can translate when the Celtics are watching most closely.

Former Celtics Big Man Just Landed A New NBA Opportunity
Charles Basseys NBA path took another turn this week, and it traces back to a brief stop in Boston before he found a better fit elsewhere. The big man spent a short stretch with the Celtics on two 10-day contracts during the 2025-26 season, a run that gave Boston a look at his size and energy but not much time to make a real evaluation.
Bassey later caught on with Golden State, first on a 10-day deal and then on a longer stay, and the change of scenery clearly suited him. His play with the Warriors stood out well beyond what he showed in Boston, which is why this latest contract news matters for a player still trying to turn fleeting opportunities into something more permanent.
