Sticking to players who are in the regular rotation ... right now, probably Kyle Lowry. I'm always intrigued by the new guy.
Without a doubt Scola. He is just fun to watch. I always like the crafty players (I also liked Mchale in the days).
As much as I hate the Celtics (we should have beat them in '86), I've got the utmost respect for Bird, Parish, Ainge, Johnson & "cough, cough", McHale. Although dubbed "the Black Hole" by many McHale was one of the best "power forwards to ever play the game" - just ask Chuck... Scola could've taken him though.
I could really care less about the effort/hustle/heart most people discuss when they talk about favorite players. I enjoy watching talent and skill. Scola has the mid-range game, the post game, he can put the ball on the floor, and he runs the break. On another team i think he could average 17 and 10. I'd say he's my favorite rocket right now.
