You're missing the point, though. His performance was based on his ratings.
Not vise-versa. I realize that that's not how it is in the game. That's what I'm saying: the game is flawed in that way. Fortunately it's not a game-breaker yet, but it easily could be. It is completely and totally the opposite of "sim."
In fact I'll go one further: I know a lot of people liked Head Coach and are excited that the HC people are working on Franchise. I'm not. I won't play HC. It is not a sports simulation game. It is an RPG. The depth elements are good, but making Madden rosters the correct size, choosing an active roster on game day, cutting players pre-season, all seem like they would take 5 minutes to do.
