Top 15 as of October:
1 Fedor Emelianenko
2 Brock Lesnar
3 Antonio Rodrigo Nogueira
4 Frank Mir
5 Josh Barnett
6 Shane Carwin
7 Junior dos Santos
8 Brett Rogers
9 Randy Couture
10 Andrei Arlovski
11 Alistair Overeem
11 Cain Velasquez
13 Fabricio Werdum
14 Jeff Monson
15 Gabriel Gonzaga
Mir is a joke being that high, imo. Fedor dominated NOG and was supposed to fight Barnett until Barnett got caught juicing. He is going to face Werdum next. If he wins, he will fight Overeem for the title. That will be the 3 fights on his current contract. After that, who knows. Maybe Dana will get his head out of his arse and promote the biggest fight in MMA history. I kinda doubt it.
If Rogers thinks he is going to get Overeem next, he is dreaming. You don't lose and get a shot at the Champ.
