I know you're all football guys, but this kind of thing would work brilliantly with baseball.
Baseball gives you day to day games, different pitching matchups and so much data. You can get heat zones for anyone, pitch type values, etc...
Baseball so easily fits a data driven model that it's perfect for simulations, etc...
I don't know if your present framework could ever be easily modified/adapted for baseball as well, but "fastballsimulations" would be pretty damn sweet and would likely be even more addicting due to the day to day matchups and machinations involved.
Just a completely random though...(one 'out of left field', you could even say)
If you can't draw a crowd, draw dicks on the wall.
