As for the Hayden allegation, I think that argument is more directed toward their football program than any other sport, considering they are the smallest school in their league by far and win their league title pretty much every single year.

But as far as wrestling goes, thetiger makes an excellent point about the kids clubs. STA has a very good kids club program, and it you look back to when STA got its kids club program going, their high school success followed suit about four or five years after that when the kids club guys entered high school.
Look at the strongest programs in the state year after year, and it's likely that they have strong kids club programs. That is no coincidence.
