The Big 12 may not be done poaching schools from the Pac-12, even after adding Colorado this week.

The Big 12 would prefer to add one more school to bring their membership to 14, according to Heather Dinich of ESPN

"Fourteen seems to be our best number," a source told ESPN. "Now that we're at 13, who's going to be the first to make a move to start having a conversation with us was the general discussion today. We talked about a lot of different schools, but it's more about, 'Hey, we've got room for one more and who wants to be the first to really want to be a part of the Big 12 now and join us?'"

Sources suggested that Arizona may be the league’s primary target, but that school may wait until the Pac-12 concludes a media rights deal to make any decisions about its long-term future.

It certainly feels like open season on the Pac-12. The conference is already losing UCLA and USC to the Big Ten next year. Colorado’s exit is raising further questions about the conference's long-term future. That may prompt other schools to look for alternatives, particularly with media rights talks dragging on.

Reports have indicated that the Big 12 is casting a wide net regarding potential expansion, but Arizona makes sense from a lot of perspectives. While they would round out the numbers overall, their basketball program would also be appealing given its track record of success.
