Why are there so many different opinions about this young man? Its been mentioned that he will go 19.90 this year, sub 44 seconds in the 400 meters next year & now there are concerns that he won't have enough gas in the tank to get through the qualifying rounds at the World championships.
To be sure, Usain will be ready to compete. His performances this year are no flukes. This is by far his biggest challenge & he knows it. He probably won't strike gold but he could grab a medal. No matter how he fares, the experience will bode well for him as an invaluable learning experience. I am looking forward to seeing him compete on TV for the first time.
