Celtics Roster Plans Just Got Tougher After A Surprising NCAA Twist

The Celtics face a challenging roster dilemma as NCAA's decision impacts Dillon Mitchell's NBA future, revealing a missed opportunity with John Tonje.

John Tonje’s departure already complicated Boston’s two-way picture. Dillon Mitchell’s NCAA ruling just made it messier.

Not long ago in Las Vegas, Tonje looked like the Celtics’ best summer league performer. He scored, he shot it, and he showed enough in handling the ball and on defense to stand out in a crowded group. After arriving in Boston from Utah at the trade deadline in February, he seemed like a strong candidate to land another two-way deal with the Celtics for the 2026-27 season.

For a while, the path looked fairly clear. Boston kept an open roster spot, then used one of its three two-way slots on Amari Williams.

That left the expectation that two more openings would go to Mitchell and Milos Uzan, the rookie point guard from Houston who also impressed in Vegas. The remaining question was whether the Celtics would give Mitchell the 15th roster spot to keep everybody, or make the tougher call and move on from one player, most likely Uzan.

Then Tonje signed with the Trail Blazers last month, taking a two-way deal that came with two guaranteed years. With that kind of security, and with Boston’s situation still unresolved, he moved on from the Celtics.

At the time, that at least seemed to leave Boston in position to keep the 15th roster spot open and bring back both Mitchell and Uzan on two-ways. But an NCAA ruling allowing Mitchell the chance to return to college for a fifth year has thrown that plan off course.

Mitchell hasn’t decided yet, but the money angle is obvious. He’d likely earn more in college than he would on a two-way deal in Maine. Boston could try to keep him by offering a standard contract worth $1.7 million, though even that might not top what he could make by going back to school.

If Mitchell does head back to college, the Celtics’ path gets even more frustrating in hindsight. Tonje would have had a cleaner route to a two-way spot, and Boston may have ended up losing him without really needing to.

Right now, the Celtics have Williams on one two-way. They’ll likely use another on Uzan, which would still leave a third two-way slot and the 15th roster spot available.

That gives them options. Tucker DeVries, who also received a training camp invite after a strong summer league run, is one possibility.

Boston could also look elsewhere around the league for another two-way target. The problem is simple: it’s going to be tough to find someone as good as Tonje.

He already showed he could dominate in the G League last year, and he’s spent several months developing in Maine. With Mitchell now potentially headed back to school, all of that may have gone to waste.

It isn’t a disaster, especially for a player who may never become an NBA rotation piece. And Tonje may have preferred Portland regardless.

Still, with this latest Mitchell news, it’s hard to avoid the feeling that Boston may have let a promising 25-year-old prospect walk away for little or nothing.

Celtics Fans May Not Love Brad Stevens Next Move After Brown

Jaylen Browns move to Philadelphia has already forced Boston into a familiar kind of recalibration, and Brad Stevens now has to decide what comes next for a roster that still has Jayson Tatum at the center. The talk around the league is not about replacing Brown with another headline name so much as how the Celtics can keep enough flexibility to stay competitive while avoiding the kind of cap squeeze that can trap a contender for years.

For fans hoping the front office would swing big again, that softer approach may be a tough sell. The current thinking points more toward adding useful players on value contracts and staying aggressive in the trade market without chasing another supermax star, which leaves plenty of room for debate about the direction Stevens chooses and which targets actually fit the path Boston wants to take.

Brad Stevens Still Has One Huge Celtics Question To Answer

Brad Stevens has spent the summer making the kind of hard choices that come with living under the NBAs second apron, and the Celtics reshaped roster shows just how serious Boston is about threading that needle. Moving Jaylen Brown for Paul George and draft assets was not a decision made for comfort, but for flexibility, with the front office trying to stay competitive around Jayson Tatum while also keeping enough room to adjust later.

The next test is whether those moves actually buy Boston the kind of control it wants over the rosters future. The Celtics have also brought in young players and are managing contracts with an eye toward keeping options open, but the path forward still depends on how Stevens handles the timeline around George and the rest of the cap picture. Even after the biggest transaction, the broader question in Boston is still unsettled: how far can this group go now, and how much can it pivot later? [Read more 🡒]

Celtics Dream Target Would Change Everything Around Jayson Tatum

The idea of the Celtics making a splash for a true franchise-changing star always turns heads, and the latest dream scenario puts Stephen Curry and Nikola Joki in the conversation. There have been no confirmed trade talks or offers, but the mere possibility of Boston chasing a player of that caliber says plenty about how the team could try to reshape the roster around Jayson Tatum if the right opening ever appeared.

Joki stands out as the more natural fit in that kind of hypothetical, especially because of the way he changes an offense and eases the burden on everyone around him. He has also signaled a desire to stay in Denver, just as Curry has with Golden State, which keeps this squarely in the realm of speculation for now and makes the next offseason worth watching closely.
