The CFP sequence was a classic display of ND arrogance and hypocracy.
1) They actually argued head-to-head matters less than some end of season beauty contest.
2) Thier AD picked a fight with weakling ACC over UM, while being too afraid to take on the SEC despite having 5 teams in the playoffs.
3) Too special to play in a bowl game; trying to punish the world for not being selected.
4) Too special to join a conference. Why buy the cow if you can get the ACC milk for free.
5) Exerted leverage for special guaranteed future playoff bid with one loss; no other team gets similar treatment
6) JL bragging about hurdling a UM defender despite being held to 33 yrds
It's nothing new. Over the years we've endured their holier-than-thou (literally) attitude, thinly-vailed racism in characterizing UM as thugs and convicts, endless excuses (they intimidated us in the tunnel, our bus was hit with a bottle, our academic standards are so much higher, etc).
The great thing about scheduling ND is they are reliably overrated, so one win and you're in the title discussion (assuming head-to-head matters, haha).
