My friend loves the NFL, he's originally from Michigan but moved over here in his teens; still watches it obsessively and heads to London each year for the superbowl.
He's trying to get me into it. I've tried on several occasions to immerse myself and I'm getting there...but, can somebody please explain the rules to me like I'm a three year old? I get there are two phases of play that each team goes through, the offense and defense, but how does the points system work outside of touchdowns? Does it go purely off yards that are covered? It seems complex to me, even though I'm sure it isn't.
