Those of you who follow the site know my feelings on Derrick Brown. He's very athletic and seems to have a pretty strong defensive acumen. Players out of Xavier always seem to and yes I apologize for the generalization.
Brown doesn't have a particular position and I think, ideally, the Knicks would like to see him develop more range on his jump shot so they can sneak him some minutes at the 4 position in this system. But I think he can really be a solid, two-way transition forward for the Knicks and a player that, at a good salary rate (aka NBA dollar cost average) he can provide some value and be developed into a rotation player or a trade asset.
It's hard to say if they get that chance because they have to decided if they are going to offer him a contract. There has been talk of Brown returning to the Bobcats, where he saw much more playing time. Right now, he isn't an NBA rotation player for a good, sound playoff team, but he has the stat sheet-filling ability to be one at a good cost in my opinion. If I'm Melo or Amar'e I lobby to bring Brown back.
