UFC 118 picks, Vegas-style: Who wins the overshadowed title fight?

B.J. Penn is always the star of the show but not this week at UFC 118. The Hawaiian lightweight legend has willingly taken a back seat to James Toney. The boxer's talk and promotional acumen has carried the card. But make no mistake about it, Toney against Randy Couture, from a pure fighting standpoint is a sideshow (Sherdog's pro's picks have it 50-3 for Couture) compared to the UFC lightweight title rematch between champ Frank Edgar and Penn.

Penn lost the first matchup via unanimous decision back at UFC 112. In typical Penn fashion, he's tried to drum up some drama and angst heading into the fight but it's just not that easy against Edgar, who is pretty benign with the spoken word. So the issue again for Penn is motivation. Is he fired up? Will he alter his style and work harder for the victory? If not, he'll have two losses in a row and then what motivates him to come back and get better?
