Yeah, some of these posts are showing how some of us haven't gone down the realignment rabbit hole. It's all about expanding footprint and academics (if that's your thing).
ISU isn't moving up the totem pole, ever.
KU has the AAU but lacks the football or borders with a B1G state.
KU is sort of in a purgatory, unless the SEC made a move west and added an OK school with it.
.
Clemson wouldn't jump into the SEC, as good a program as they are.
It would be UNC and a VA team, or if UNC's academics got it into the B1G with UVA, then NC State and VT would join the SEC.
Hell, in either of these cases, the Big 12 others and the ACC others would join to form a very good conference. Both cannot go on existing on a long timeline.
