Athletes ocean has lots of good resources from what I hear. I think they even have things that teach you how to structure practices. You might also want to seriously consider bringing in someone with wrestling experience to be on your football staff. Definitely need someone with experience to be a wrestling coach or you'll be holding your athletes back in terms of technique. I help out with football at the school I coach wrestling at (middle school). Helps to build a relationship with the athletes before wrestling season begins and it gives you the opportunity to get kids excited about trying a new sport and potentially recruit more.
