They are a few percentage short how is this the worst thing in the world? If we class wrestling we now have an even distribution across the board. 50% and 50% when there is a much smaller group of people to compete against and still win a state championship isn't this an even BIGGER advantage for small schools than the few percentage problem we have now??? I would go on to bet that if we increased the numbers slightly to include more wrestlers at state we would see the numbers come a little closer to what they should be...
But the fact is it is a combination of all those things. (Genetics, skill, mental toughness, coachability and so on...)
