I find it interesting that ISU and Ku's president/chancellor are on the expansion committee with TxT and BU's athletic directors. That sends a strong message to me, at least, about ISU and Ku's future, i.e. they have no plans to leave the B12.
It shouldn't. Any move to the B1G would likely await 2025...and absolutely has to wait until after we've settled with OU/UT. In the meantime, unless you're a peawit, you plan for the worst case scenario of staying put...and that means adding at least a couple of teams in the short term. So adding teams tells us NOTHING about what may or may not happen with B1G/Pac expansion in 2023.
