Change one event in boxing history.

[El Kabong]

Box history & world history would have to be re-written.
Jack Dempsey, gone & the dude that America's Hollywood made in his image (Clark Gabel) wouldn't of been able.

Gable would have still been around...Dempsey might not, but he wouldn't be a bum. Sam Langford would be THE household name and he'd take shine off of Jack Johnson's star that's for certain.
