For me it's Ali/ Frazier Everybody in the world knows this two fighters and almost everybody knows Ali's trash talks before the fights. The others were also great rivaly's but here in germany for example only real experts know the other fighters.
If I was old as **** I may have chosen AliFraizer. I picked barrera vs morales because I actually watched all those fights as they were happening and was excited over them. Ali Fraizer happened before I was born and thus all I can do is watch already knowing how it is going to end, no drama in it for me.
I'd say in my lifetime, age 33, the best one was Barrera Morales. But there have been meny that were not mentioned. What about Gatti Ward? Or Paq Marquez? Holyfield Bowe? Or Bowe Golota?
Wlad and the canvas. Wlad has hit the canvas numerous times during his career. The canvas can't seem to keep Wlad off of him.
