Amar'e is a lot better than Chandler is offensively now, but I think Chandler is more smooth. I think Chandler might be able to get a consistent hook shot, and judging from his foul shots, he seems like he can at least be a decent mid-range shooter.
I still think Amar'e needs to work hard on his ball-handling. It's erratic like J.R.'s, and a lot of times it was plain bad. A post-up game from him would definitely be great, but he rarely has even ever done that, so I don't know how much he could improve on it this summer, whereas Amar'e already has the ability to handle the ball and stuff, just needs to be consistent.
