Ask any coach, speed kills! If you have someone who has decent skills to add with that speed, you have an instant threat in attack.
Now, a coach needs to use that player correctly because defenses can play against pure speed, but if he is decent with his feet, he might be ok in that league. I don't see him moving up to the bigger teams though, outside publicity reasons.
Who doesn't know Bolt right?
Do you think his lightening speed would work in football? Im not sure how good his technique and feet is, but with basic football ability his speed and athelic body would help.
Do you think he would succeed? Can this be a new beginning for runners to join football? (loll like we dont have enough kick and rush football already)
