I'm a knicks fan(kinda, I'm a nets fan but they've sucked crap for so long I'm kinda just slipping into knick fandom lol, I've never disliked the knicks) and meh, Lin coming back isn't a big deal, at the end of the day he is just a backup PG that got hot, he's not THAT good, and that was totally exposed when they played the heat and got killed. The big thing they need is to get Amare back and have him playing well with mello, then they can really make a go at the finals.
It's imperative the knicks make a push and get to the 6th spot, there's no way they're gonna beat the bulls or heat in the first round.
