Wladimir Klitschko punched himself into exhaustion in that fight.
You have to give Brewster respect for his great chin though! He was on the verge of being stopped and weathered the storm. Then Wladimer couldn't pick his arms up any longer.
Wladimir Klitschko has had conditioning problems. He also doesn't have a fighter's heart and he has a questionable beard. I saw his other losses to Corrie Sanders and Ross Purity. He gave up in the 11th round to Purity. He hates to get pressured. His brother Vitali also quit against Chris Byrd.
