Is there a single place on the web that will give you everything you need to understand the game. I know all of the basics and am familiar with a good deal of terms and dynamics of the game, but I am looking to better understand the plays themselves and the science behind knowing what defense to line up against a particular offense. I assume this means I am looking at strategy as well. When I see a particular line up for the offense, I would like to know what defense should be lined up to combat it and why. I would like to hve a better understanding of the general dynamics of the game beyond the basics.
