It was always strange to me that a guy who came into the league with a rep as a pretty good shotblocking center became such a non-factor once he got into the league. Best I could come up with was that weakside rotations were always his weak point on defense, and he never really put himself in position to block a lot of shots. It used to drive me crazy how he'd have his head turned towards his man while guards could just drive it right to the rim behind him.
Seems like he's operating as a weakside defender at a much higher level than ever before. His BLK% is at a career high 4.6% (previous was 3.3% in his rookie year before going downhill from there), he seems to be always in proper position when the initial man gets beat, and his overall defense at the rim is much better:
