Floyd is the best boxer of his generation. You SAW skills. You saw how he adjusted and what that means. Floyd was better, skillwise, than Roy Jones. Just that Roy was a better athlete with superior hand speed and quickness.
Floyd hands down (I say grudgingly), as Pac was ~sparked out~ like a log, stone cold by Marquez. Floyd never even more than wobbled by a Sugar Shane Shot, and once again by Zab.
