I agree, look what happened Vlad Klitschko when he lost to Corrie Sanders, it almost wrecked his career!
He was pretty much hand fed opponents he would walk through, then Sanders blasted him out in two rounds. He come back against "Touch of sleep" and got put on his arse again and looked shaky as hell before winning then the Brewster fight lol f**k me he was in the horrors. He ain't done too bad since but he had to make a lot of changes to get to where he is now.
