Yep, the average fan watches the snap, the QB until he releases the ball and then where it ends up. They rarely watch routes, the defense being played, or the battle in the trenches.
I go overboard. I love the game so I usually watch it a couple time. DVR is wonderful. I have now watched the iowa game three times (less painful each time). And actually slow plays down. The game wasn't as bad as I first thought. Herman needs to adjust better though.
