He is a weak runner. He came in 8th in the 100 meter run, and gatlin and tyson were really fast.
And considering that this was tyson's first run, his body and legs had more energy. He was fast as hell on his leg, probably the fastest, with gatlin being fast as well.
It should have been brommel to gatlin and then to gay, clearly. ...gay and gatlin are the only runners who have beaten Bolt.
