I've learned quite a bit about the strategy of football over the years, and I would say that I have a decent grasp of football strategy for a fan who only played pee wee football and have never coached the game, but compared to any coach or player my knowledge is pretty weak. The more I understand the strategy of the game, the more I enjoy football. So, I would really like to learn more. Where would y'all recommend going to learn more? Books, videos, etc. Thanks!
