The first couple guys that come to mind are Joe Frazier and Jake LaMotta. They faced the best mover their divisions ever produced and had real success against them where other greats didn’t.
Chavez: Camacho, Lonnie Smith and Meldrick Taylor were way faster than him on the feet but he was able to wear them down. Whitaker should have won against him but Sweat Pea was comfortable on the inside with Chavez.
Henry Armstrong Joe Frazier Julio Cesar Chavez Prime Roberto Duran Harry Greb Roman Gonzalez Jeff Fenech Fighting Harada Not an aggressive, swarming type, but I can't see him being properly out-boxed below 175, and that's Tommy Hearns.
I hate to be that guy, but that wasn't Tyson at his best. I'd say an example of Tyson dealing with a good mover is his fight against Holmes
So we can't use an active 24-year old Tyson, but a rusty 38-year old Holmes if fine? That pretty must sums up how Tyson fans argue about his career imo.
