I love fedor but brock will smash him. This is not a knock to fedor he is a legend but sometimes a man is just to big. Lesnar would just go for the take down and gnp fedor. I know fedor is capable of submitting him but unlike big foot lesnar will be more aggressive with his gnp.
fedor could fight at middleweight if he really wanted to you know, h e never cuts weight and he has a gut like rogan said, but even lhw he could make nicely
