Vitali threw a lot for a heavy. Ibeabuchi threw 975 punches against Tua so he has to be come there. Frazier in the first Ali fight was a frickin non stop that night, may not have thrown a record number of punches, but the pressure and head movement was just relentless. At lower weights, Phillip Holiday, Margarito, Calzaghe, Pacquiao.
Vitali and Pacquiao were different and special athletes. No 240 pound man should ever have that stamina. Vitali really was incredible. And Pacquiao is the only guy I know who could be full blast for 12 rounds. Just nonstop power all night long.
Mayweather would've UD williams, if you think I have a dumb opinion see this poll http://www.boxingforum24.com/showthread.php?t=223423 19 votes, 19 UD Mayweather Just like the Mayweather vs Margarito poll that ended up around 74% saying Mayweather wins.
