Don't believe its realistic to expect Chandler to become a real post player at this point in his career, but I believe it wouldn't be a bad idea for Tyson to have an up and under move he can go to once in a while.
One thing I'd really Chandler to work on (as well as Melo and Stat) are his technical foul calls. Melo was ranked second, Tyson third, and Stat seventh. I know they got some bad calls this season but those techs aren't helping, and at times they have hurt the team.
