Agreed. Going forward they are going to have to go create random rosters and maybe include a disclaimer similar to the one you see in the credits of movies - "All characters in this product are fictitious. Any similarities to real-life persons are purely coincidental." In the end that may not be enough, but it could calm the fears of the schools out there who are on the fence about continuing to be a part of the game.
Losing rosters that are accurate would be a big loss but it is the lesser of two evils - losing a slew of schools and having to go back to the "University Park" days with generic uniforms and stadiums would be the end of the game.
