I think this is a pretty close matchup but im gonna go with Griffith by a very close decision, Griffith almost stops Norris in the late rounds while scoring a knockdown 8-6-1 Griffith.
A "pre Paret" Griffith could stop Norris. Griffith had a good jab so it's conceivable he could catch Norris and get him out of there, but I'll say Griffith by decision.
That's wishful thinking. I'm sure the way my boy whipped yours has something to do with all the hateration
I'll go with that great jab to score the points. Griffith also had those terrific whiskers and Gil Clancy would have his guy not doing the things Norris could capitalize on.
