BOISE - Conference realignment has once again emerged as a hot topic of discussion throughout college football. And once again, Boise State is at - or at least near - the center of that discussion.

The landscape started to shake Tuesday afternoon when the Big 12 Conference announced that Commissioner Bob Bowlsby had been authorized to once again explore expansion. Interestingly, the conference will consider adding football-only members.

That led to a tweet from USA Today Sports writer Dan Wolken who claimed expanding from 10 to 14 teams, and adding BYU and Boise State as football-only members makes sense to him.

Thursday Wolken joined The Press Box from the Big 12 Media Days in Dallas and explained why he thinks Boise State is a great choice for the conference.

"That's just my idea for what a good expansion move might look like," he said. "Boise State's positives are very clear, and the negatives are very clear. The question is going to be, what direction does the Big 12 want to take this expansion?"

Dennis Dodd of CBS Sports chimed in Wednesday as well, saying that there are many unknowns about Big 12 expansion at this moment, and that yesterday's news contradicts the direction conference leaders had claimed they were going.

So far, the conference has not laid out a timeline moving forward.
