I’m going with Patterson by decision. Mac Foster has the power factor but I’m not totally certain how well his punching ability was tested. Has kind of a weak list of wins
Floyd likely finds him. Mac had the power, but not the accuracy and set-ups of Ingo with his legendary Cooper, Machen, Patterson streak.
Foster could punch but was no Liston. Best I can imagine him doing is flooring Patterson. But I think Patterson stops him.
