I don't know why the Knicks didn't sign him in the first place. He will excite the fans a bit, he will put up ungodly stats, and most importantly, why the hell not? Are they really trying to groom Duhon or Robinson for the future?
Right now, their goal should be putting an entertaining product on the floor, and hoping they can somehow convince an elite player or two to join their abomination of a team next summer.
Oh yeah, and I have AI on my fantasy team, and if he joins the Knicks, it will make the reach worth it.
