The End of the modern SEC will be when Texas, Alabama, Georgia, and Florida leave the SEC for a new Super Conference or the Super Big 10. They will then give Auburn, LSU, TAM, and Tennessee a chance to leave with them with lesser terms.

Then the "SEC" will become:

Arkansas, Missouri, Kentucky, Vandy, MSU, OM, South Carolina.

We will be left to fight for scraps of the ACC implosion like Louisville, Virginia, Virginia Tech, Georgia Tech, and NC State.

May not be that bad
