Can someone please explain football to me? For example, the lingo and the positions and such. I'm dating a football player and I always liked watching I just never fully understood the game. Thank you so much in advance everyone!

It is a pretty broad question but check out this link and everything will be explained.

PS I don't think you are a dummy this just really explains what you are asking!

Haha no hard feelings. Thanks for the help!
