It wasn't that Tunney was getting bigger, it was Grebs said he just gets better and better. And Grebs would have won absolutly no fight against a modern fighter. In the first round, he'd start getting drity with lacing, elbows, back fist and so on. He'd be DQ inthe 2 or 4th round for head butting Holy, punching Gollada in the nuts and bitting off Tyson's ear. In a time of dirty fighters the King was Greb.
Tunney spent a week in bed after the first Greb fight.Loughran said Greb had inhuman stamina,"he started fast and just got faster".I think Greb has to make anyone's top 5 P4P. I really can't split him and Langford for the top spot.
While Greb was a dirty ba5tard he could fight clean if he wanted too. It was relativley late in his career that he became the foul Pitsburger.
Actually it was both in the first fight Tunney weighed 174 1/2 to Greb's 162 1/4 by their 5th and last fight he was 181 ,Greb 1671/2.and a t 6 foot to Greb's 5 8 he had the frame to fill out.
