First off - Good luck this season!
Having been on both sides -- wrestling in the city, and coaching for a year after college in another city -- I think a lot of people said some good stuff already, but wanted to note something:
While it is about teaching the sport of wrestling, don't think they can't win those state championships or AA's. I think the most important thing I brought with me as a coach was that I treated my athletes as if they'd win, and I was willing to go with them to whatever level was necessary for them, as they are, to win. Every other facet of life while growing up in the city has the approach of having to do more to be at the same level as everyone else, and that's no different when it comes to sports.
The kids will put in the work if they have someone believing in the work that they're doing. It might mean taking some time in the off-season to coordinate rides to club practices, or fundraising for tournaments and bus fare, or even writing up an accessible diet & workout plan, but they'll do it!
