Wrong, I never said Sugar said it the quote I was referring to, only that he is one of a few who thinks Greb head butted Tunney in round one. Greb could be dirty you know. When did Tunney back out of the contract? Details are needed. He was probably making more money elsewhere, like a million dollars to fight Jack Dempsey the next year for the heavyweight title. Ya think?! Why would he need Greb again, he just whipped him. Greb's quote is telling. Leave it to boxing false bravado, just like Dempsey singed to meet Wills when he knew the NYC commission would vote against it, forget the fact the fight could have been moved elsewhere. Greb did not want Tunney again, unless of course he could make a lot of money in exchange for a beating.
