I think the weight difference is a big factor personally and I've mentioned it several times. PW was just fighting at 147 about a year ago. This is a mismatch, but people can't see it because they just don't want to. They'll jump on it when Williams gets stopped though, just like some of KP's faction cried about him fighting Hopkins at 170 after he lost. KP weighed 174 on fight night to BHop's 180, per HBO stats. Bhop was 43 years old. PW's style and size disadvantage give him a tough task to overcome. Winky Wright and Pavlik present two totally different orders to process.
Then he should be fighting Middleweight's. Pavlik-Abraham would have been so much better. Pisses me off that it never happened. :verysad
