I posted this originally on a football website, and got no useful responses. So, I figured I'd post it here, where there might be some others who went through the learning process I'm currently going through. 
I've never been a big football fan, but this year a few friends roped me into playing fantasy football with them (to make the number of teams even) and that, coupled with the Panther's doing well (I live in North Carolina), has awakened in me an interest in the game.
However, I just don't know much football. I know the basics that anyone growing up in America knows: The Quarterback usually throws. Wide Recievers usually catch. Running backs run. I know the basic penalties, what the line of scrimmage is, et cetera. But once you get past that, I'm a complete idiot. What is a tail back? What is a full back? What is a half back? Why are they called half- full- and quarter backs? What are the basic formations? What do they look like, so I can recognize them? When is a fullback eligable as a reciever? Why do offensive lines sometimes get called for false starts when one guy twitches, but other people on the line can run around in the backfield? What are the names of the positions of the people doing this stuff?
These are questions whose answers are basic knowledge to my friends, but I don't have the foggiest notion (and I feel dumb asking them). And there are probably lots of other questions I don't even know to ask.
So, my question is, can anyone point me to a good guide to football that explains things simply and effectively? I need a crash course in football, but most web sites seem to assume I already know the basics. Help!
