greenes 2001 world champs remains the greatest in my mind because he was on track to do amazing things into a headwind. his 9.79 and 9.80 are close behind. Powell is awesome running two 9.77s. gatlins 9.77 is the fastest 100m ever run, and the fastest second 50m ever run. dont get too carried away though, as more stats are coming after i weed wack the lawn, along with ideas and such for discussion.
