I wouldn't list Mike Tyson on here.

When I think of complete fighters, I think of guys who can fight at all ranges, who can box on the move or be aggressive, and use different styles if necessary. Tyson had a nice heavy jab for his size, but it wasn't like he was going to win a fight on the inside. He had to do his damage at mid-range or when he was coming inside. He was also prone to laziness on the inside.

Marvin Hagler is someone I think of when describing a "complete" fighter. He boxed well and used the ring well. He could apply pressure very well. He could fight on the inside. He had solid defense with his parrying. He wasn't blazing fast, but had pretty respectable speed, and heavy hands as well. He could take shots well.

Floyd Mayweather's not the biggest puncher, but he has respectable power. He's fast, smart, can box on the move, fight on the inside, apply pressure when he needs to, attack the body, defend, etc...I'd consider him a pretty complete fighter.

Roberto Duran, Ray Leonard, Bernard Hopkins....all in their primes I'd call them complete fighters.
