I can think of a lot of fights where Fedor seemed to be losing and then, well he just won the fight. Mirko, Nog, Hunt, Arlovski, Coleman, Randleman and even Lindland all had moments when they were winning and Fedor found a way to turn the tables and dominate. Brock will bring a physical presence and athletic combination that Fedor hasn't seen before but you just have to believe that Fedor will find a way to finish Lesnar.
