As of Madden 09 I can't tell you anything
I'VE learned, but when I first started playing Madden in the mid/late 90's it taught me some things about the game of football.
I guess you can say my idea of 'sim' w/ Madden09 is a realistic score/outcome.
The CPU AI doesn't doesn't really have any 'I' so I can see what you're saying when it comes to getting 'sim' results from the CPU.
