I have been involved with a youth football program for 10 years and have yet to see a kid burn out in football. The kids that have graduated from our program are having great success at the high school level and the coaches know which kids have played before and who are new. We are a county wide program so our kids can go to 6 different high schools and our program starts with 6 year olds! We talk to al the high schools and they thank us, telling us that they can get into play calling quicker because the kids know the fundamentals of the game already. Talk to your local high school coach. Find out what he would like to have kids know when he gets them and try to run the drills and play calling style, hole numbers ect. Good luck.
