What is Theis's ceiling? Can he develop an offensive game?
Let me say that I love Theis as a player. Great effort and understanding of the game - a real pro - and an absolute steal on that contract. That said, I think his ceiling is very good backup big or poor man's starter. He's already 25, and he's been a pro for a long time, so I'm not expecting huge leaps forward in his game. On offense he's going to be a decent shooter, hopefully continuing to improve from the NBA 3-point line; he's capable of a straight-line drive to attack closeouts if there's a path to the basket; and he'll set good, wide, solid screens at the perimeter. Those are all useful skills(!) and he's a willing and pretty mobile defender. But he's never going to soar like AD or AG, and he doesn't have the same strength as the bully bigs, which makes him susceptible to being pushed around a little by the true centers. I don't think he has anything like Kelly O's ability to use fakes and change of pace to get to the basket.
