If Dawson had such a pathetic chin, why was he never stopped before? Not against Glen Johnson, Adamek, Tarver, Hopkins, Pascal, etc, but goes down in weight and is stopped by....Ward? Same thing happened to Roy Jones. Or Chris Byrd. Not to take away from Ward's performance, he's awesome, but Dawson has a huge body frame. His trainer advised against it said it wouldn't be healthy and he was right. Dawson was wobbly from the first shot.
If you're going only by the last year, then sure Stevenson is higher. But Thats not how one generally makes a pound for pound list. Contender fir fighter of the year, yes.
Also as I mentioned before, in divisional ranking you have to rank official wins and losses. A robbery counts. Pound for Pound is different, so Pacquiao, in the eyes of 99%, has a win over Bradley and a loss to Marquez in his past two fights. Bradley is obviously a higher quality opponent than Dawson or Cloud.
