NFL/college football games are too long. I will only watch an entire college football game when its an A+ game (my opinion of A+). I will only attend college games when I know they won't be on TV (I hate "TV timeouts".). I have other things to do than spend 3-4 continuous hours in front of a TV.  An entire NFL game I will never watch, if at all. I hardly even take an interest in the Superbowl and playoffs anymore. I gave up on the NFL long ago because it left the world of sport and entered the world of entertainment.

Austin is correct, Monday Night Football in the 1970/80s were "magical." If anyone wants to capture the spirit of NFL football during that time, I recommend reading the books:  "Monday Night Mayhem: The Inside Story of ABC's Monday Night Football" and "The Last Headbangers: NFL Football in the Rowdy, Reckless '70s - the Era That Created Modern Sports".  How it all started? Read, "The Best Game Ever: Giants vs. Colts, 1958, and the Birth of the Modern NFL".
