This guy has been amazing since he was a string bean. If you're the best in the world for your age at age 15, 16, and 17...it's not so crazy to imagine being the best open athlete by the time you're 21 or 22. It doesn't always work out that way with youth athletes, but in this case it clearly did. You can see the major talent at a young age.
If MJ ran 19.32, why couldn't Bolt run faster? If Tyson Gay ran 9.69, why couldn't Bolt run faster?
