There ius some great footage of some real greats;
Mike McCallum
James Toney
Roberto Duran
Bernard Hopkins

Battling Torres was terrific.
Pipino Cuevas was very good inside.
Hank Armstrong was a machine.
Shame that we dont have na lot of footage of Greb.
The eras of LaMotta, Basilio, Zale and Fulmer saw some vicious inside fighting - but was a bit blood & guys for my liking.
The 90's had some good inside fighting - Chavez for aggression and Whittaker for more slick stuff. Michael Nunn could do it and do it well.
