I think Mir's head's still feeling the effects of Brock's hammer blows...
If the fight goes to the ground, Fedor doesn't need to get back up. He'll just slap that infamous armbar of his on Brock and win that way. You really can't faze him or scare him with a vicious ground and pound assault. I honestly wish I could say otherwise, because I'd really love to see someone challenge Fedor, but I think this is the truth.
