Because structure and rules are what make games and competition possible in the first place.

Because some degree of competitive balance drives widespread interest and is essential for the sport.

This is such a fundamental concept, and it boggles my mind when people take out their frustrations on the NCAA's admitted failings and the so-called exploitation of student athletes by advocating for the wild, wild west. As if F1 would be better without agreed rules; as if the NFL would be more fun if players could withdraw from a team at any point and join literally any other team at several junctures throughout the year.

Pursue this "lack of regulations" lark long enough, and you'll turn CFB into even more of a joke than the NBA—it will draw regional interest from the handful of programs willing to consistently pay the most/get the dirtiest, and will wither on the vine everywhere else.

And, for what it's worth, the inconsistent (some would say selective) enforcement of these rules is one of the CFB's biggest problems. Big teams can tamper without repercussions, but heaven knows that if everyone starts tampering it will be the Boise States and BYUs of the world that suffer for the modern equivalent of a VW Jetta or some couch-surfing.

Say what you will about coaches and ADs and their lack of loyalty, but I don't think we've ever had a coach resign 2-3 games into the season in order to coach another school, but we're already seeing that from players...
