Its hard to say what calibur, but A team like Notre Dame should have a top 10 or close class year in and year out. So assuming that you take in 25 recruits which seems like the average. you should have say 3-8 five stars, 8-15 four stars, and the rest three stars with maybe a two star thrown in.
Unless you cheat, even at your best, its hard to constantly get the #1 recruiting class year in year out. I average in the top 10 and have only gotten #1 when i cheated (i controlled other teams ahead of me and withdrew scholarships from players i really wanted...
)
But if your recruit to the best of your ability it would be hard to cheese up the game. It actually seems like this is a new feature that EA didnt overdo
