With the lack of championship ready fighter depth in the MW division, you'll probably see Leben fight Franklin so that he can get a shot at the title vs. whoever wins Swick/Silva in February. Nate M. would be a good fight and he deserves the fight but they probably won't do it because Levben sells PPVs (like him or love him, people watch him especially since he became a highlight reel when Silva destroyed him)
The problem the UFC is having is that they have a huge stable of LW and WW fighters but only a few real contenders at 185 lbs and 205 lbs. I can't think of anyone outside of the TUF4 and the top 4 UFC MWs that make up the division. There isn't anyone new out there in that division.
Fedor sleeps with a night light. Not because Fedor is afraid of the dark, but the dark is afraid of Fedor.
