IIRC, Lyle was the one who learned boxing while in a Colorado prison. He was that perpetual underdog you tended to root for. He lived longer than Joe Frazier.
Lyle said in prison when he had nothing to do he would do push ups. He got to where he did 1000 in an hour.
He was a much more likeable personality than the Louisville Lip. The ref stopped his match against Clay whith Lyle on his feet and not in such serious trouble compared to what he triumphed over in other fights.
