I didn't see much in Lesnar to be honest, most people could have finished Mir from the top like he was doing and his hammer fist didn't seem like they had much behind them. And as predicted he was leaving his arms out all over the place during his ground and pounding leaving him self open for millions of submissions attempts.

Just in case you don't think the stoppage was fair for Lesnar, count 4 blows to the back of the head. fucking rookie isn't worth the money Dana put in to if he keeps that up. I wounder what kind of pot Joe Silva is smoking when he thinks its a good idea to put a Glorified Newbie Wrestler against a BJJ Black Belt in his first match when trying to make him the next champion.
