​A Wisconsin Badgers legend left a notable imprint on an NBA Summer League game, showing remarkable resilience and an ability to rise to the occasion when it mattered most. After a relatively quiet start, John Tonje surged in the second half, pouring in 20 points to lift the Boston Celtics to an 83-80 overtime victory over the Toronto Raptors. The performance highlighted his drive to reclaim a spot in the NBA lineup for 2026, a goal rooted in his prior stint with Boston and his determination to prove his worth.
Tonje, now 25, had spent the previous season with the Celtics, appearing in six games and averaging around 7.0 minutes per game. Those modest numbers masked the potential and the chip on his shoulder—an underdog mindset that fuels his approach to every opportunity, especially during summer league play where each sequence can make a difference in one’s professional trajectory. His latest showing in overtime suggested that Tonje is not willing to wait for opportunity to come to him; he’s prepared to seize it.
In the game, Tonje logged 26 minutes, finishing 6-for-14 from the field and shooting exceptionally well from beyond the arc, going 5-for-9 on three-pointers. His accuracy from three-point range was a key factor in Boston’s comeback and eventual win. Across the stat line, he also contributed five rebounds, three steals, and two assists, underscoring a well-rounded two-way impact that the Celtics value in their development players.
Crucially, every one of Tonje’s 20 points came in the second half, underscoring how he found another gear when the game intensified. His late-game savvy culminated in a decisive play during overtime: a steal followed by a dunk with 22 seconds remaining sealed the victory and demonstrated his ability to finish strong in crunch moments.
There’s ongoing buzz about Boston’s remaining two-way contract slots. NBC Sports’ Raphielle Johnson noted the two-way market in Boston, suggesting Tonje’s standout summer league performance could position him as a prime candidate for one of those coveted slots. With his performance in this game, Tonje made a compelling case that he can contribute meaningfully at the NBA level and deserves consideration for a two-way deal that would keep him in the Celtics’ system while further developing his craft.
For fans following Wisconsin basketball and John Tonje’s professional journey, this performance adds another chapter to his story. It demonstrates that a player who once wore the Badgers’ colors continues to pursue every avenue to compete at the highest level, leveraging the platform of the Summer League to showcase his abilities and push for a stable spot in the NBA.
