and I would say the success of Carl Lewis is meaningless, the 100/200m track event has come on leaps and bounds since he ruled, so his success means monkey shit!
Or lets say Tom Burk, he did 100m in 12 seconds pre 1900, so that meant nothing and means nothing now.
Or Jim Hines, first man to break 10 seconds, held the record for 15 years, its meaningless because of how fast Bolt is now...
