Man the Lakers have no heart. They are a bunch of bitches. Houston barely has enough guys to put on the floor and are coming off a 40 point whipping and the Lakers can't be bothered to finish them off. This is why I generally don't like the NBA. Too many teams with that attitude of play hard only when they feel like it.
Don't let one team or one series ruin your opinion of the NBA. There are a lot of other teams who play their asses off and have a ton of heart in this league.
