Carlos Negron is living proof Size doesn't always win the prize. Can you name some examples where skills pay the bills? Ones that come to my mind: Chris bryd once fought at 140 pounds. Dat craftiness doe, all the way to heavyweight Of course Manny The Vet beating up huge welterweights using his skills.

It's a pretty rare type of skill set and natural acuity to become very good in a weight class that you're physically outgunned in and dont have height/reach or speed/power against the opposition. Maybe the rarest of the rare, you're turning a BIG disadvantage into an advantage. Gotta have strong legs because it takes a lot of knee bend and movement from the waist up. James Toney always comes to mind(assuming it's the version that shows up to fight)
Miguel Canto and Ivan Calderon. These guys were the Latin version of Willie Pep who weren't hard punchers at all but relied solely on their pure boxing skills and slick defensive technique despite the opponents always being bigger than them.
Duran Canzoneri Qawi Lomachenko Pacquaio Patterson Greb Alberto Davilla Mclarnin Harada Basically, alot of top 50 P4Pers.
