Azumah Nelson, because he's the only old guy who didn't fight like an old guy and either get beaten up looking for the knockout punch, or try to spoil and steal a fight. His stoppages of Ruelas and Leija in 95-96 at the age of 37-38 are easily my all-time favourite old-guy performances, ****ing magic.
one of my favourites nelson was. if you're going to add that then we may as well add duran v barkley too...for fairness sake.
Hopkins. The guy in his 40's has beaten and fought great guys and not been knocked out. Amazing. Although eventually his age will be a problem. He is turning 46 in January. That is way too old for a nonheavyweight. A heavyweight could fight at 46 since most of them are old and lazy, but not anyone who has to make weight. Bernard is incredible.
