Chandler will never be a good offensive player. He should be able to add some more weight and a couple more feet on his jumpshot, but his offensive game will mostly be dunks and putbacks as long as Skiles is the coach. His role is to play defense, block shots and crash the boards.
Too bad he sucked at all of those things last season. I'll give him (maybe) another year to see what he can do with a capable big man.
