What is Steven Jackson 40 yard dash time?

Answer 1

It is said that Bo ran the 40-yard dash in 4.12 seconds at the NFL combine. I think that might have been hand timed.

NOTE:

Many reported times are unreliable due to differences in timing methods if not intentional falsifications. The NFL did not begin using partial electronic timing (started by hand, stopped electronically) at the Scouting Combine until 1990. In track and field races, the runner must react to the starting gun, which can take 0.10 to 0.20 seconds. For electronically timed 40 yard dashes, the runner is allowed to start when he wishes, and a timer hand-starts the clock (after a reaction time of 0.10 to 0.20 seconds). Although the 40-yard dash is not an official race in Track and Field, the 60 meter dash is an official distance in indoor track and field, with the world record for that race being 6.39 seconds (run twice by Maurice Greene, and once by Ben Johnson, whose record was annulled for Steroids). The fastest 60m split time is probably 6.32 seconds by Asafa Powell, in his 9.74 second 100m World Record run in Rieti, Italy. Fast starting elite sprinters such as Powell (and others past and present) can run a "Football 40" close to 4 seconds, because the sprinter does not have to react to the sound of the gun, and the starter has to react to their movement before the clock starts. In the 2001 World Championship 100m final in Edmonton, Greene covered 30m in 3.75 seconds running time and 40m in 4.64 seconds running time, putting his 40 yard (36.576m) running time at about 4.24 seconds. Given a hypothetical timer's reaction time to Greene's motion, Greene's "Football 40" time for this race would have been between 4.00 and 4.14 seconds. There actually is no single, "official" 40 time at the NFL Combine. National Scouting, which runs the combine, provides three times per run, two fully hand-held and one stopped electronically. Each player may run twice, thereby yielding a potential six times. National Scouting provides all six of these times to NFL teams. The teams then do what they want with those times, or ignore them. Some teams use the best electronic time. Some teams throw out the fastest and slowest and average the rest. Some teams use the best time provided. And some teams use a time provided by their own scout on site.
