Hopkins pulled off a lot more big upsets than Floyd, but to be fair Floyd has hardly ever (if ever) been an underdog.

Someone explain to me also how going up in weight and dominating Tarver is any better than going up in weight and beating Canelo Alvarez?

Tarver was a solid fighter and the #1 at LHW at the time for sure, but he had 3 losses on his record and had been beaten by Glen Johnson just a few fights previous.

Canelo was the #1 at his division too. Young, undefeated and has gone on to regain the #1 spot in his division now that Floyd has dropped back to WW.

Someone explain to me how the Tarver win is a much higher quality win, because I don't get it.
