Milesplit says he didn't race the 100m last season. He did run 21.20 in the 200m and 46.15 in the 400m, plus longjumped 24-2, which is tough (though not impossible) to do without elite 100m speed.

I guess I just don't think you're ever going to find signs from previous seasons that a highschool athlete is going to run 10.13. The age-group heroes like Tyrese Cooper who get, like 10% better every year starting in 7th grade are the exception, not the rule.
