There is actually some really quality match ups in here. Count me in for a match up with Baylor vs. Oregon or OSU vs. Cincy or even Utah vs. OSU...
However, does this move the needle enough to guarantee a playoff spot? An undefeated team in the Big 18 vs. a one loss non-conf champion in the Big 10 or SEC would be really hard to put in there IMO.
Let's say a Bama goes undefeated and Georgia is a one loss
Ohio St. wins the Big 10 and is a one loss and Mich or Penn St. is runner up with one loss.
I don't know how you can deny the Big 10 and SEC runner ups auto bids vs. a Big 18 champ. The SOS is going to matter exponentially now. Unless you just give auto bids to the super-conf champs and one at large conf champ from the ACC and then a team like ND.
Even now, if the Big 18 comes to fruition, it's not going to really bolster the league into respectable super-conf territory.
