Aside from pac who in this era has the best stamina in the welterweight division.?

Even when he's been pushed hard or has fought a much more aggressive fight he's never gotten tired. Even if we're talking moving a lot in a lower output fight...it's way harder to move for 12 rounds, duck, bob, slip and weave than it is to throw more punches while walking forward. Floyd doesnt constantly move, duck and weave though, he is very economical with his movements, and patient he doesnt waste energy, he times your punch waits for it and moves or slips he is also on the defensive he slides back instead of lifting his feet, he is brilliant at saving energy, he doesnt waste shots in fights though, if you dont think throwing more punches with intesity and moving forward expends much energy, you are mistaken, bradley started tiring after throwing bombs at manny in the second fight, and bradley has great stamina. We really dont,know how good floyd stamina is at welterweight since he doesnt throw many combos in a fight. In the maidana fight he was constantly on the move and still didnt let his hands go, he constantly tries to hold, he is similar to wladimir klitschko in terms of economical output, both back step and bounce. Back and tie up, wlad has bad stamina but if you never seen his fights before when he threw combos and gassed bad, you would never guess it, you would think he had great conditioning and stamina.

floyd never tires but that's probably more to do with his low output. Paul Williams and Tony Margarito are 2 obvious ones people always mention. Margarito and Williams definitely. Both big Welterweights with a very high output from as well.

mayweather has more stamina than pacquiao. twice daily he sparred 20 four minute rounds every other day leading up to the pacquiao fight How is training or sparring harder an indication of Mayweather having better stamina? Pac fights at a fast pace, Floyd fights at a slower pace (most of the time), but either way I've never seen Pac or Mayweather gassed out, so it's really impossible to really tell who has better stamina between the two.

Margarito?

I think the only time I've ever really seen Floyd tired was against Augustus.

Currently, it's gotta be Bradley, possibly Porter. Looking at other big names, Williams would have to be up there.
