As much as I can't stand Melo, the guy can offensively take over a game like no one besides Kobe in this league.
As great as Lebron is, if I needed 15 points in the 4th quarter, I'm probably going Melo. That Easter blowup was exactly why he'll be hovering around these lists for the next few years, a supreme offensive talent.
Regarding Rose being "overrated", it'll be very interesting to see if his explosiveness is there in 2012/13. He is ridiculously quick and a great finisher, but without his explosiveness he isn't going to get the calls he always relied on before. It'll be interesting to see.
EDIT: It'll also be fascinating to see how the Bulls respond without Rose early this season. They got worse and worse without him, and ultimately they are just a "very good" team. With Rose, bordering on elite. Still would've taken Miami/Boston over Chicago last season, but I think a healthy Rose this season makes them the clear #2 in the East. I'd be pissed if I was a Bulls fan.
