I always root against Mayweather. Now, I am not a hater. I see with my own eyes the amazing skill he has. But there is something about him as a boxer that I suspect is lacking and I think it is his chin. For years I suspected that of Roy Jones ever since Lou del Valle dropped him, but Roy's defense was so good that none was able to test his chin until Tarver and Johnson came along. I think it's the same with Mayweather. No one will be able to test his chin as long as he keeps fighting the Gatti's the Baldomirs the fading de la Hoyas, who doesn't commit to his punches as he used to.
