Everyone has an opinion but I think you are very off on this one. They have a horrific football program in a small population state that is declining in population every year. Add in that they would be second lowest school from an academics standpoint (only Nebraska is lower) and you essentially have a non starter.
Washington is in a growing state, great football program, and excellent academics. Oregon is similar with lower academics but an insanely good football program plus the direct Nike ties.
Well before the new big ten deal was being signed Kansas came calling and the big ten told them there was no way.
It all depends on how basketball is viewed going forward. Basketball has essentially funded the rest of the NCAA making it much less valuable than it should be. If these leagues are serious about splitting away, the basketball tournament could become just as big of a financial boon as the CFP.
To put it in perspective on how the NCAA has screwed basketball schools.
CBS TV deal - $1.1B annually
Payout per unit (1 unit paid per team for each game played): $338,000 x 6 years per unit = $2.03M
x 67 units in each tournament = $136M paid to conferences of the participating teams.
So the NCAA keeps roughly $1B annually and that's not including the ticket sales. Where since the football playoffs are separate from the NCAA, all that profit goes to the conferences, making football more valuable than basketball. And also why I doubt the NCAA tournament makes it to the end of the contract in 2032.
So if basketball is pushed to follow the football financial plan, suddenly a basketball school like Kansas starts to make more sense for a conference to covet.
