Yeah, like others have mentioned, how is it supposed to know where you intend to go on the field? How is it supposed to know that you want to run or stand still? I guess they could have you run in place but that would get old fast. And, I suppose it could tell how hard you threw the ball by the speed of your arm motion but how is it supposed to know which receiver you're throwing to?

It's an intriguing idea but I don't think it's an executable one.

If you choose season mode instead of franchise mode, then you can already do this in The Show 09.
