@PRHusky , valid points for a 12th team, specifically the NCAA Tournament revenue.
But the league wants a 20 game conference schedule. All of the P5 conferences are going to 20 games. Our options are play 20 and have better games on the resume for selection Sunday or play 18 and fill 2 games with cupcakes that don't move the needle. We want to be playing Nova, Creighton and other Q1/Q2 opponents twice a year to help our metrics. The committee showed this year that "beating up" on each other in league play is rewarded with top seeds, as the undeserving Big 10 was rewarded with 5 top 4 seeds.
Granted, they could still do a 20 game schedule with 12 teams but it wouldn't be as clean.
