Don't understand the current LSU/Kiffin kerfuffle at all

I understand the controversy over the Class of '22 and the extra year of eligibility and the rules regarding professionalism, but what I don't understand is this. Why is LSU being singled out with lawsuits and threats of sanctions and expulsion by the conference?

I mean, several SEC schools (Mizzou, A & M, Kentucky, Ole Miss) have players on their roster against the old professionalism rules. Kentucky has Alex Afari, who had to sit out week one to make sure he clears waivers from the Packers. A couple of years ago, Alabama played a basketball center who had actually logged minutes in an NBA game. The SEC has allowed all of this, but when Kentucky wanted to bring Mark Mitchell on to their roster, it seems like people in the SEC offices lost their minds.

All of this will eventually be resolved, but it will be in the courts or the Halls of Congress. Since we are dealing with universities, whose primary purpose is supposed to be the well-being and growth of the students, the decision will ultimately likely come down to protecting the rights of the players to earn money, freely move around to where they can maximize their potential earnings, and in favor of the players in general. The courts will take a dim view of all of the inconsistent enforcement of the rules by the SEC and NCAA.
