I’ve always wondered if Madden’s legacy as an announcer was tarnished a bit by the video games. It was magical having him dynamically announce the game you are playing, but the sophistication was limited, especially in XBox/PS2 era. I remember his voice saying generic silly things about the games I played as much as I remember the real games he announced.
IRRC, he also said he focused on explaining the game to someone who wasn’t a fan yet. It sometimes drove lifetime enthusiasts nuts, but I appreciated that he saw his role as making a complex game accessible.
