Shane Battier has a lot to do with it. Only time I ever rooted for Duke. If you could pull the trigger and pull in any one role player in the NBA, I'd bring in Shane Battier.
I'm also an unabashed Tracy McGrady fan, I don't know why, I just am.
EDIT: Well I mean I know why i like Tracy McGrady, when he's on, he's one of the best guys to watch in the NBA. Although, I will say since last years game 1 in the finals, Paul Pierce has officially taken that mantle as "most fun guy to watch play when he's on fire"
