I think the funniest thing about all this is the SEC just literally set a nuke off in their own backyard, hoping to kill their neighbors. At some point everyone in college football is going to look at this thing, the SEC included, and go, "Oh ****, this is a mess". If you want to realign college football you need buy in from everyone to do so.
The only real move here by everyone else is to stop panicking and trying to grab teams, take a second to breathe, and say, "You're going to form a new "league" of college football without Clemson, Notre Dame, Ohio State, Michigan, Miami, FSU, USC, Washington, Oregon, Wisconsin, Penn State, Nebraska, Stanford, UCLA, etc?" What's left in college football is collectively a better product than what the SEC currently has. I say you isolate them away and say, "Fine, go form your own league with your 16 teams." And then you figure out a way to realign with everything else. You could really ***** them over if you did this right. A 16 team SEC league is not going to outperform a realigned college football if it's done right.
