BJ Penn is a horrible coach (Ultimate Fighter 5)

Right, I understand that Dana White wants to create drama by constructing the team rivalry, but the question is why do the fighters buy into it? Like this season, that Nathan Diaz jackass was ready to go to war over Team Pulver being the traget of some grafitti. Maybe if I was in the house as a fighter and had never seen an episode of the show before I’d buy into the team concept the way he did, but looking at it from the dispassionate outside it’s ludicrous.
