I have to disagree, Brock can and will be beat and just about did, a different Ref may have called that fight as Brock was doing almost nothing but taking shots for about 15 seconds straight, the bottom line was that Carwin just flat gassed out. After the initial shots Brock took he backed off and ran and then got dropped, his eyes were a bit out of focus and he was not to far from being out. To his credit he was able to stick it out absorb the punishment and get back into the fight, had Carwin not run out of juice he would have put Brock out, but 3 minutes into the round Shane was out of gas.... The bottom line in MMA is that on any given night ANYONE can lose, all it takes is a mistake, a small mistake and you can get submitted or knocked out by someone not nearly as good as you. Brock showed he can take a punch and he showed some heart by staying in there under a lot of blows, but he also showed he can get hurt and flat does not like to be hit in the face by a guy with some serious power. Brock can and will lose again, the difference will be if he is able to become a more rounded and better fighter and come back and win again after every loss or every fight for that matter. He is showing signs of that every fight, but no fighter is so bad@$$ that he wins every fight every time particularly with the caliber of opponets that he will have to face.
Well said X2.
