We have definitely seen bench lose a double-digit lead in a matter of minutes. We have also seen them come in with a double-digit deficit and tie the game. I think the problem is that there are no established roles on the bench. If the starters are doing well, the bench sits. Even if you play extremely well in the first half, it doesn't guarantee that you'll get any playing time in the second. I think it is one of Flip's flaws that even though he says that the playing time is earned, the reward is not always there.
