Browsing the NCAA forums over at OS gave me the idea for the most challenging OD yet. All user teams start off with a one-star team of made up of nothing but seniors in season 1, so that in year 2 you start off fresh with only 25 scholarship players on your roster (think UAB after they dropped football then started over). For fun, user teams could also be thrown in conferences with 5 and 6 star teams. I'd probably never win a game! We'd just do recruiting in Year 1, simming the games.
Not that I'm actually proposing another new OD...
I just love kicking around new ideas.
