I think the only team I would not feel 'angry' about winning would be the Spurs. The teams in the east is rather self-explanatory, and in terms of the west, I can't say that I do not enjoy watching the Thunder, but I absolutely detest when the officiating takes over and it becomes an absolute FT fest. I've seen that a few times watching them.
So..
Spurs are my clear "second" favorites, followed by Thunder. Between the rest I could not really care less, as long as the Heat or the Lakers wont win.
