This one may be entirely impossible to catch. Like Pete Rose's hits record, it requires an average season to be absolutely superhuman; even if a player were able to maintain his incredible foot speed throughout his career, he'd still need to average 94 steals a season over a 15-year career to get it done. Do you know how many people have stolen 94 or more bases in a season in MLB history? 29. How many have done it in the last 25 years? None. Quite simply, the de-emphasizing of steals in modern baseball has virtually eliminated any chance this record had of getting broken.
