Laidback most of the time, Usain Bolt rarely misses out once serious competition gets underway When we were in Grade 3, he made the senior cricket team, with boys in Grade 6. He was eight, and he made the team with 11 and 12-year-olds. Thats when we knew he was special. We always said if it wasnt track and field, it wouldve been some other sport because he was that dominant in any form of sports, he added.Not that his mates always made the best use of his speed. Especially on the football pitch.Hes very good on the flanks, continues NJ. Obviously because we could utilise his speed. But funnily enough we thought hed be a good goalkeeper.
