The Big12 recently added Colorado as their 13th member but it has remained clear they plan to continue expanding. In the short term Arizona has now been named the very likely 14th addition to the conference.
The Big12 has targeted 3 teams in particular in Arizona, Arizona State, and Utah. The Big12 is “putting them on the clock” and accepting whoever wants to come in next while slamming the door on the other two(atleast for now.) Arizona is seen as the preference of the three.
The reports also state that if all 3 of those programs say no then the conference is going to pursue UConn as the 14th. However the members aren’t as sold on adding UConn do to them being buttcheeks in the sport of football.
