Look at all of his fights at 130. I use to get into debates with the fellas at the gym about what was Floyd's best weight. To me it is clearly 130. The man did have power at the weight, he was an offensive fighter with even better precision, his footing was like he was gliding, not to mention he was quicker, threw more combinations and to me the only thing that is better at the higher weight is his shoulder roll. At 135, Castillo was a bit rough so he didn't look as good and at 140 you see some of his stuff slightly lessened but not far off and at 147 its very noticeable. He had to fully develop the shoulder roll, use more hit and not be hit punches, and throw very few combinations. The 130 Floyd is the best fighter I've even seen. All the other weights I can place him in various scenarios as even or a slight underdog.
