Mickey Walker is an anomaly in even the incredible era he fought in...I like him here against the vicious Norfolk (although it is unfair to judge a fighter's merits off of only one or a few clips.) I believe Walker demonstrates the footwork to offset Norfolk's leaping left hooks by either crowding or stepping back then countering. Walker's fighting posture positions him to avoid right hands, and places him in a position to counter or lead with left hooks. Walker's timing with those left hooks against the jabbing master Loughran was fantastic. Norfold would be much more physical than Loughran, but less difficult to time and gauge. I like Walker by decision.
Im going with Norfolk. Norfolk could fight a very controlled and contained fight with nice sharp accurate punching. That and his size and strength I think would give Walker problems. It would be a hell of a fight though and I could see both guys tasting the canvas.
