Never heard of anyone running a 40 at a track & field meet.
It was Binford’s speed that got him into football in the first place. In college, the 6-foot, 185-pound Binford took part in an intramural track meet at the University of Missouri-St. Louis. He was timed with a 4.22 40-yard dash, and those watching advised him to turn that speed into a football career.
