I remember the Atari football game. The players were squares with legs and I think you only had like 3-4 players per side.
I also remember getting in trouble at school by playing a handheld game during class. It simply used red dashes to represent the players.
Madden may annoy some people when he points out the obvious, but the man knew the game inside and out. He is going to be missed. I like Chris Collinsworth, but he is going to be the anti-Madden. I would like to see Terry Bradshaw get out behind the desk and get in the booth.
