I haven't heard, is the Big 12 going to 20 league games next year or sticking at 18? I'd prefer 20 even when we have 12 teams, but it should definitely be 20 with 14 teams.
You're hurting your league by not giving yourself more Q1/Q2 win opportunities. This is a super hypothetical, but imagine if we had 18 games this year with the 14 teams, and our 5 extras were BYU, Kansas, Kansas State, Oklahoma, and Texas Tech (these are random other than BYU and KU, but I'd hope the league gives us Kansas and K-State twice next year). Maybe you drop the BYU road game so you only go 6-4 in your home/aways, get stuck with only playing Texas and West Virginia on the road, you get Cincinnati and UCF at home, and all of a sudden your Q1 record starts to look a lot worse as you stack up a bunch of useless Q3 wins (or potential Q3 losses). Hypothetically, we need Cincinnati, UCF, and BYU to either improve or become total cellar dwellers where they're a guaranteed win. Adding a handful of Q3 games where you could still maybe lose does nothing positive for you.
