Honestly I'd rather just play more conference games with the new teams coming in. Those games are going to feel very non-conference for a little bit anyway.
Is there any hard news about number of basketball games in New Big 12?
I assume it won't stay at exactly 18.
After OUT leaves you'd need 22 to keep the full round robin.
For the weird 14 team year we could do what B10 does at 14 now and have 7 teams home and home, 3 just road, 3 just home for 20 total.
