Since Dana has confirmed that GSP vs Alves will not be the main event at UFC 100, the big question now is who will headline the event? In the video above, Kevin Iole and Steve Cofield discuss the possibilities, and seem to think there’s a chance Randy Couture is one part of the equation. If so, could Fedor be the other? Doubtful, but Iole thinks it makes sense, although he also makes it clear that its only speculation on his part.

Rashad Evans vs. Rampage/Machida makes the most sense to me. Any other guesses?
