Seriously, everyone knows that BJ Penn is one of the all-time best draws in UFC history. Out of everyone on this card, he's the only one who is a legitimate draw. I understand that a title match takes priority over a non-title match, but having Rua-Gustafsson as co-main event doesn't make much sense to me. In fact, I bet most people are looking forward to the Penn-MacDonald fight over every other fight on this card (I know I am).
