Gault is still the fastest player in the NCAA.
Not sure about his time but Green was a legit player...His best was a 10.10 100m which is stupid fast but just off the top of my head Trindon Holiday, Jeff Demps, Darrel Green and Jacoby Ford had faster times.
Actually Gault wasn't even the fastest UT WR, which was Leonard Scott with a 10.05. Actually Scott went on to run a 9.91 though that was after college. Still AFAIK that's the fastest 100m every run by anyone that played legit football.
