When Wariner was in high school, he did have one of the top 200 times (20.41w). And he is going to run some 200's next year.
You're comparing a 43 second guy with a 49 second guy. It's really no contest. For a 10000 meter guy, Bekele's finishing speed is great. But if he was a white kid named Mike Smith....he'd be just another white kid who had to be a distance runner because wasn't fast enough to do the sprints.
