Lakers have had the Nugget's number pretty much every time they've faced off against each other. With the momentum of the complete man-handling of the Rockets in Game 7 and Bynum looking like a stud (admittedly not against Yao, but it still boosts his confidence, which means a lot to a young player), I see Lakers in 6; Anthony has just sucked against the lakers in the past, and I don't see that changing too much.
I haven't followed the Magic at all this season, but I doubt they will give LeBron too much trouble. Cavs in 5. But yeah, considering I know jack squat about the Magic, I wouldnt be surprised if I'm dead wrong here.
Lakers against Cavs: doesn't hurt that this is the game that everyone wants to see. Lakers are just too deep for the Cavs though. Lakers in 6, even though I want to say Lakers in 5. Lakers' roll players are just way better than LeBron's supporting cast.
