4. Bo Jackson, NFL
There’s a reason why ESPN ranked Jackson as the greatest athlete of all-time, because the dude was a complete freak of nature, combining speed, power and insane athleticism into one specimen that was difficult to even slow down—unless it was because of injury. Standing 6’1″ and weighing 230 pounds, Bo ran an insane 4.12 40-yard dash, making him appear to be something of a fake human being. It’s a shame he never reached his full potential due to the aforementioned injuries that slowed him down during his two-sport career.
