This is awesome for me to see, I'm the biggest Deion fan in the world and I've never been able to find the truth behind his 40 time. There are rumors of all types all over the web.
Back then the combine got very little media attention, it was nothing like it is now. There is no video footage of Deion nothing.
So anyway, the truth of what actually happened is, Deion showed up to the combine in a limo, got out, didn't stretch, ran the 40 once, got back in his limo and left.
He was clocked by 4 different people hand timing at 4.27, 4.27, 4.29, 4.33
And now I know, what really happened.
