Why not make Werdum vs Cain?
At least Werdum in his last 3 fights defeated Fedor, lost to Overoid and destroyed Nelson.
He is 4-1 in his last 5 fights. That makes much more sense than putting a 1-3 guy in a No. 1 contender fight.
Make Nelson vs Russow and Werdum vs Cain instead.
Damn, even Mark Hunt vs Cain would make much more sense.
