how many 5th graders (10-11yrs old) were playing? "Good genes"?

Averages are just that. Higher end of the curve=lower percentage of the population.

Express's "good genes" coupled with "good recruiting"..... and it still doesn't make sense based on the average height/weight for 12 year olds. Too many kids seem to be on the high end of the curve.....
