The fool who said JJ Reddick is just a spot up shooter obviously you haven't watched a single Magic game this season. I honestly don't want the Magic to give him up, but if there were any other team I would want to see him on NYC would be at the top of the list.
You want Shumpert for one reason and that's to guard Dwyane Wade in the playoffs. If you move Shumpert for Reddick who guards Wade? Jason Kidd? JR Smith? The Knicks make this move and they're giving Wade a free pass.
It makes sense because Orlando is rebuilding and doesn't particularly need average players in the middle of their careers while NY is trying to win right now and Reddick will contribute as a starter or a reserve whereas Shumpert is an undeveloped young player coming back from an injury, more useful to a team that is losing in the present and looking towards the future.
