You can't possibly argue that Bynum's fouls were warranted. No way. That was a blatant cheap shot and he knew it. As soon as he did it he started walking off the court, taking off his jersey.
As to what should happen... Bynum should go. Odom has been a good player and doesn't often act that way. But Bynum is terribly inconsistent on that court and, additionally, has a bad attitude often.
More importantly, HEAT ALL THE WAY BABY!
