If he would have dived for the gold medal and got it then that means that he was close enough to win it. It is not like he dived a 100 meters. Gatlin would be a hero in America tonight if he would have dived and won that medal over Bolt. They would be talking about how hungry and tough Americans are.
diving running 100 meters at top sepeed, and diving almost out of breath at 400m is totally different, you'd prob end up tearing or breaking something but hey gatlin is what 34, go ut ona stretcher with that gold around your neck
