The summer league isn’t usually any more predictive than any other five game stretch, and to Sarr’s credit he’s averaging 2.5 blocks and 7.7 rebounds. He’s also averaging a solid 3.2 assists for a big man.

However, with all of those disclaimers, what Sarr is doing in the summer league is historic. Even looking at the worst star summer league performances, from Trae Young to Jaylen Brown, they were all scoring twice as much and usually twice as efficiently.

Sarr was always seen as a prospect that would need some development offensively, but it’s possible that he won’t be able to play the role that he envisioned long-term

I used this source which also gave a couple of limited advanced stats.
