It would be fantastic if he develops into a starter, but even as a role player he could be an interesting piece. A rotation guy who wins a playoff series someday due to matchups, able to defend the post, switch on to 3s and 4s, and shoot the 3.
Big Baby with a better head on his shoulders, 3PT ability, and more defensive athleticism would be a fun guy for years to come...
He could also never develop, but he's definitely intriguing.
