I think the problem I have with this boo him or not thread is the context of the moment. They boo'd him before he had even stepped on the court. They boo'd him after he had to sit there for two months and watch his team fight and change and become something different than when he left it. The two months he was spending rehabbing an injury and trying to come back to play for the team we cheer for. I guarantee you he cares regardless of what ridiculous assumptions we come up with on boards like this.
I have no problem booing Bargnani. I just won't do it generically. I will do it if he's in the game and he's personally responsible for a particularly bad stretch in a game. The whole point in cheering and booing is in reacting to what is actually happening in the game...if it's because you hate a player...then you need to get a f*cking life...seriously. It is still a game.
