I'll watch anyone that is on and consider it a privellege to be able to do so.
I like watching the young exciting teams like the GSW and the Thunder, the proven vets like Boston and the Lakers. Watching great players do their thing like Nash, Melo, Paul, LeBron (at least I did!), Howard etc.
All in all no matter what the game I will watch it and find something to like about it which isn't hard as the NBA is such a great league.
