Bolt is a pretty improbable sprinter too from the look of him. Like when he started dominating a decade ago, I figured, 'Ah, that's the future of the game and soon lanky guys who only need like 4 strides to cover the distance will be dominating the sport.' But it hasn't happened, at least in my limited observation. You got Bolt - and a bunch of compact, powerfully-built guise - and Degrasse.
