When I think about Fedor's opponents and who did the best I personally thought Coleman looked the best in their first fight up until the point Fedor pulled off that sick arm bar from the bottom. Coleman had taken his back and was controlling the fight. The man to beat fedor has to be able to physically impose himself on Fedor. Your not going to win a slugfest(the man took Fujita's best shots) w/him so either you use excellent grappling technique combined w/ superior athleticism to keep the fight standing up and wear him down or take your chances w/GNP(not suggested). Randy has shown great wrestling and athleticism, but he has also shown that he can be ko'd. Randy would be game and have some good moments but eventually would either be brutally TKO'd or ref stoppage from a sick submission.
