1968: The Dallas Cowboys draft 6-4 wide receiver David McDaniels in the second round, due in large part to his 4.40 40-yard dash time, recorded on a track at Mississippi Valley State University. At training camp, McDaniels looks slow compared to the defensive backs and is re-timed at 4.73 seconds, at which point the team finds out that the college track is short by a yard-and-a-half. Later, the Cowboys save face by trading McDaniels to the Chicago Bears—a team that also timed him at 4.40—for a second round pick. To this day, all NFL scouts measure to make sure the course in question is exactly 40 yards.
