Favorite "guilt-trip" player (i.e.: player that you like more than you should and so feel guilty about it):
Kobe Bryant
Explanation is in order: (a) I don't like him as a person; (b) I don't like him because he's a Laker; but (c) I think he is a fantastic competitor and a fantastic talent. While (a) and (b) bring him down, I can't completely ignore (c).
