Yeah? How? You realize Clottey will not drop his hands and Floyd doesn't hit harder than Pac. How will he land more to the head? Explain.
It would be a UD for Floyd but not as dominant. But styles make fights so that means nothing when comparing Pac vs Floyd where Floyd holds all the style advantages
The Clottey/Floyd fight would have been like this [yt]<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/lbrQNgA8k2g&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/lbrQNgA8k2g&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>[/yt]
Floyd would've "fought" Clottey in the media with words (if prompted), knowing that the name & money involved aren't worth risking his undefeated record to fight someone whom very few people have looked good fighting against.
Mayweather would have tried surgical precision shots. He would have landed more but had thrown about half as many punches.
Floyd would have won just as easily as Pac did, but he wouldn't have thrown as many punches. It would have been a much duller fight.
Mayweather would have done pretty much the same thing in a different way. I say a 118-110 type decision in his favor.
