Nigel Benn vs Emile Griffith

I have a hard time seeing Griff ko'ing anyone at middleweight, as he had largely abandoned the ko for his crafty points earning style, but you may be right here, as he WAS capable of stopping guys, even Benn. Griffith was too damned good for Nigel Benn.

 

Benn would probably knock Griffith out, too strong, too relentless with speed to back it up
