John Tonje Shines for Celtics in Summer League

Summer League Spotlight

The NBA Summer League offers a 10‑day window for rookies and hopefuls to showcase their talent to professional front offices. John Tonje, a former Wisconsin Badgers guard who did not receive a qualifying offer from Boston, is using this chance to catch eyes. So far this year, he has been a standout performer for the Celtics during the 2026 edition.

Rising Profile and Celtics Interest

Tonje has logged 60 points in the Summer League thus far, quickly becoming a focal point for Boston’s coaching staff. According to Justin Turpin of WEEI, his solid play could earn him a spot on the Celtics’ final roster. The former second‑round pick also saw limited action last season, contributing 15 points, six rebounds, two steals and two assists across six games.

College Career Highlights

During his lone season with the Badgers, Tonje averaged 19.6 points and 5.3 rebounds while shooting a impressive 46.5% from the field. His offensive firepower helped the Badgers finish the 2024‑25 campaign with a 27‑10 record. Unfortunately, the season ended in a 91‑89 defeat to BYU Cougars in the round of 32, and Tonje earned recognition as an AP All‑American Second Team selection.

Roster Implications

If the Celtics decide to fill their last roster spot, Tonje’s Summer League showing could be a decisive factor. His blend of scoring ability and defensive energy mirrors the kind of versatile guard Boston has sought in recent drafts. Observers from WEEI note that his performance may influence the front office’s final decision, especially given his prior experience in the NBA.
