I'm not overly concerned about his offense. We all knew that the hand switch was going to be a short-term loss in terms of overall offensive ability in return for, hopefully, a long-term gain, and it turned out to be exactly that. What I'm worried about is his defense, where he's gone from a shot blocking menace in college to a complete non-factor in the NBA. While with his offense is developing according to plan (although it's a very unorthodox plan), his defense may actually be regressing, and it's not totally clear why. His scoring, passing, and rebounding numbers are all around what they were in college, but he's averaging half as many steals and one sixth as many blocks. His gradual progress on offense is meaningless if he continues to be a liability defensively.
