He was probably referring to real football. The flaw with his argument is that 99.5% of us in this country will never be able to put on an NFL uniform, or even play College Football. For most of us, the farthest we get is high school ball. So, for most of us, this is the closest we can ever come to suiting up on sundays. That is why we request the game to be so realistic. We don't get the nuances of football playing in the backyard. And most of us cannot play in the NFL, and this is our chance to feel what its like to be peyton manning reading defenses and making solid calls. And there is a strong satisfaction with that notion.
So while is it "just a game," that argument is tired and old. The ultimate fact is that there is ZERO REASON why this game, with all the modern technology, cannot play more realistically than it does.
Please, come up with a better argument than that. I know you can. For most of us, this is our NFL, so d@mmit, it better be just like it.
