A lot of support here for the idea the Big 12 should only invite Arizona State and Arizona to start.
Now, maybe in reality the reason the four corner schools are talking is because they know the Big Ten is taking a few more.
Also, maybe the Big 12 is content taking 4 and if Washington and Oregon are available later you grab them too.
Personally, I wouldn’t mind seeing UW/UofO as a third color on the Big 12 sheet.
And who knows, maybe they decide Seattle is too far and we get ASU, Zona, Oregon and Colorado.
