Good matchup The Witherspoon who gave Holmes hell, vs early 70s Jerry Quarry My pick is Witherspoon by close decision
My gut says Witherspoon. He was more technical, had more tools, bigger and more of a tank when it comes to physicality, taking and giving a punch. I think he would not be disturbed by Quarry's punches. Spoon could roll and catch them, and fire back big shots that would wear Jerry down--including a big number of overhand rights off of the roll. I think he would be able to stop Jerry late.
