Track speed and football speed are two different things.
Chris Johnson when he is motivated is one of the fastest NFL players in the league and it might be a little far fetched to think he would have any chance against Usain Bolt.
“I feel like if I would have kept training for track I’d have a chance, but I play football and he runs track, so it’s totally different,” Johnson told the Tennessean. “I think I could still probably beat him in the 40. If I actually trained for the distance he trained for, I think I’d have a chance.”
The only chance Johnson would have is in the 40 because that is around the spot that Bolt separates from his opponent. I would like to see the race, maybe Vince McMahon could set it up.
In the meantime Johnson should concentrate on beating defensive backs and linebackers.
