Obviously Rigo. I'm not sure what makes Broner a better "athlete" like people keep saying, he's far more static, not as reflexively sharp, probably a bit slower. He hits harder and has demonstrated more of an inside game but none of that really speaks to what is commonly described as athleticism.
rigo for sure, and I'm a broner fan broner is about the same level as donaire who is also a skilled fighter but rigo is defo elite up there with mayweather
Rigo by a mile. And Broner isn't that athletic. He's pretty static. Footwork is slow as hell. Rigo moves so much better than him - upper body, footwork, etc. All round Rigo is just far superior.
Skill wise Rigondeaux is on another planet to Broner. Rigo is a professor of the sweet science and Broner is just a student. The Rigondeaux that won gold in the Sydney 2000 Olympics was more skillful and technically superior to Broner.
