Rumour has it the Knicks are very intrigued by Tony Mitchell, the super athletic SF/PF from North Texas(previously bama). I like the kid as well, as he rebounds, has a nba body, is disgustingly athletic with freakish leaping ability, and does have 3pt range to boot. Hes a upside kid, but could very well be a future starting PF in the league allowing Melo to slide over to natural SF.
To be honest, Shump and Mitchell, along with Melo and JR Smith would be a very strong team, full of athletic ability and overall skillz. I could see Knicks drafting Tony Mitchell. Glen Rice Jr is similar player, i think.
