Gene Tunney's book "A Man Must Fight" 1932 On Harry Greb: http://genetunney.org/harry-greb-middleweight-boxing-champion/ On the proposed Sharkey vs Wills & Tunney vs Dempsey, Series leading to the Wills vs Dempsey Superfight: "Interestingly, in 'A Man Must Fight' Tunney says that there was a very powerful lobby of influential New Yorkers who agressively championed and pressed for the Wills / Dempsey fight to be made. This would fit in with the theory that there was political capital to be made out of this match-up. Tunney asserts that when the original Wills / Dempsey fight fell through, it was agreed that Wills would fight an eliminator with Sharkey whilst Dempsey took on himself (Tunney) in a 'tune up'. The idea was Wills would handle Sharkey and Dempsey would handle Tunney which would set up the Wills Dempsey superfight that was so coveted by certain sections of the New York oligarchy."
This may well be true ,but really Wills should not have been required to fight any eliminator ,he had been the standout challenger for a long time. Thanks for the link.
