Tom Tellez said (at the AT&FCA conference) that Carl could never be a coach as he hasn’t the temperment for it, and would be lucky to last two weeks.
Like Goose said, Tellez confirmed that Lewis was that good and such a perfectionist that he often got frustrated with others and was difficult to get along with.
I tend to agree with Goose as an athlete who was at one stage clearly was the best in the world at 100, 200 and the long jump, and over such a long period of time, in several major championships, Lewis was one of the greatest T&F athletes of all time.
If I was pressed to name my top ten T&F athletes of all time I’d probably have Lewis at number one.
