We've had lots of fast guys through the years. Ron Brown was one of the fastest humans ever. Harold Jackson was a blazer. Dickerson was incredibly fast and only got caught one time by that Redskin CB who was lightning. Marshall Faulk was a 4.3 40 kind of guy and took many to the house if he got a step. Kennison, Avery, both fast. Tavon was a little rocket. Trung was fast but had no moves. Horne could get down the field in a hurry. It's important to keep in mind that some guys time fast without pads but have slower game speed while others can run as fast as they need to to get the job done. Jerry Rice was a 4.6 40 guy and no one ever caught him.
