There are some signs of improvement: fewer fouls (especially stupid fouls), more consistent rebounding, reliable defense, timing on blocks, hitting 4/5 free-throws, a 15-foot jump shot, the 20/11 game against Philadelphia, etc. He just needs to refine a couple of post moves, like a pump fake, a spin move, etc. He still doesn't get many plays called for him with Al and Millsap back.
