text: who would be he first man to beat floyd mayweather?   mayweather has been pretty dominant and is currently the top pound-for-pound boxer so it's hard to imagine anyone beating him right now. though there are some fights that could give him a little bit of trouble, "pretty boy" floyd has demonstrated that his power, speed and defense will still lead him to victory.  if mayweather moved up in weight again to fight winky wright, that might be the end of his undefeated streak, but it's higly unlikely that would happen anytime soon. unless there's a new prospect coming along or someone just gets lucky, i see mayweather retaining his pound-for-pound status for a while yet.
