Macks problem is he stands to make a lot more money by resigning, if he digs in he will be axed by Patterson and will receive his contractual buyout of almost three million but no money ongoing and no ongoing job.Because the university doesn't want to fire him and Mack knows that. So what you have here is a huge game of chicken. Mack seeing how far he can push things without the university getting fed up and just firing him instead of him stepping down.
He may not realize it but he will become a hated man among UT alums and Horn fans.
I suspect when he sees Powers and Patterson and is presented his option of a total of 13 million over 7 yrs or a 3 million lump sum as well as the bad will he will garnish if he doesn't step down, I suspect mack will do the right thing, for mack.
