Bo Jackson and the 4.12 time 40-yard dash

This has obviously been around for years. Many (maybe even most) still believe it is a myth.

Hell, I've always been eager to see any evidence of it myself (though because I watched Bo play, I've never had much doubt of it).

Interestingly enough, though this isn't evidence per se, by watching a Bo Jackson highlight video on YouTube (one that I'd never seen before that seems to have been uploaded last June), I at least finally heard some contemporaneous evidence that it actually happened.

At 13:22 of the video, the announcer (and this happened to be the Cotton Bowl after the 1985 season, Bo's last game in an Auburn uniform where he did everything needed to win but the rest of the team didn't) clearly states that Bo ran a 4.12 40.

Again, this isn't video evidence of Bo actually doing it, but it is contemporaneous evidence that football people at that time knew all about it.
