(prime) Tszyu v Pac @ 140lbs

You cannot compare Cotto's power to Tszyu. Cotto has never been a one shot KO puncher. Tszyu on the other hand had devastating power...and weight has nothing to do with it. Some fighters just possess that pop on their punches that puts their opponents on their backs...and Kotsya had that. But more than that...Tszyu was just a flat out great boxer. Great skills, fantastic timing, and very intelligent. I know we are all supposed to be on full tilt worship Manny mode...but with all due respect...Cotto was no Tszyu and neither was a shot Oscar or Hatton. Third Man, good point about Mayweather's reverence for Tszyu. It shows you that even one of the biggest trash talkers in the sport had respect for Tszyu.
