I have only seen him against Frazier, but I saw a guy who had a crushing right-uppercut, and who is willing to fight on the inside. He had surprise victory against Eddie Machen and Ernie Terrel.
ha! i just watched the frazier-ramos fight, ramos fought a gutsy but stupid gameplan trading left hooks with frazier like that. still ramos was a big heavyweight who had a hard punch who had a decent chin. in the first round he hit frazier with a big right uppercut which sent frazier backwards nearly flooring frazier.
