Who are the fighters with the most physical gifts you've ever seen? I would say Roy Jones, Wilfred Benitez, and Meldrick Taylor would be among them.
Joe Calzaghe is woefully underrated. Phenomenal sustained work rate, ability to adjust during a fight, tremendous foot and hand speed, and great power before his hands became brittle.
Shawn Porter is a freak. Very quick hands and feet, extremely strong and I've never seen him tired despite his hellacious workrate. He's not a huge puncher, but he must hit somewhat hard if he was able to do that to Paulie
the underrated tag is partly due to his association with war+en, a promoter who is notorious for getting his fighters 'a belt' and then taking the 'felix sturm path of least resistance'... not that calzaghe took a path of least resistance at SMW. but through his association with war+en, it guaranteed that no meaningful fight with jones or Hopkins was ever going to made that would give him a profile outside of Britain that's why calzaghe suffers and polarizes people internationally when his name comes up
