I don't see it having any real impact on MMA or the UFC. Very few Olympic wrestlers make the jump to pro MMA, and the ones I can think of (Hendo and Couture) are old guys who wrestled as amateurs before MMA really existed in its modern form. Today, if a wrestler wants to do MMA I would imagine they would get into it well before deciding to go to the Olympics.
Where have you been bro? Cormier? Askren?
