My history books tell me that Jim Thorpe was almost unbeatable in the standing jumps. Although he did not compete in them in meets he whipped the best in the USA at the practice track like it was not even an effort for him. Don't know if it is true but given his talent I'd have to think it was possible.
Legend has it that while checking into a hotel before the Olympics many of the USA T&F athletes were standing around and the High Jumpers started a competition to see if anyone could touch the chandelier from a standing position. The hurdlers and a few other joined in and the closest anyone got was about 4-6" below it. Jim walked up asked what they were doing and said it didn't look that hard and in his street clothes jumped up and hit it, almost knocking it off the ceiling.
Again I have no way to verify this as fact but it's one heck of a legend about a man who was legendary.
