Zab's stock will go up, but he will have to fight Margarito, or Oscar, and win for him to be back on top, because of his inconsistancy.

Floyd won't be doomed, but he will be forced to fight the Hattons, and Margaritos, or get a rematch with Zab and win his way back.

All in all, if Zab loses, it hurts him more than a loss for Floyd would hurt him.
