Just because JC came to someones mind first doesn't make them a nuthugger. Grow up. Tyson was a great mover imo.
Ray Robinson, Floyd Mayweather, Muhammad Ali, Roy Jones, Mike Tyson, Sweet Pea, Billy Conn, Willie Pep, and Nigel Benn were the best at their primes.
Bernard "The Executioner" Hopkins. To me, it's him and everyone else right now. I don't know about past guys.
Masterpiece performance. Also, against Winky, he completely neutralized Winky's jab with lateral movement.
Carlos Quintana had great movement against Pual Williams in the first fight. Also Manny Pacquiao has great movement.
