It’s been awhile since the idea of College Football Playoff expansion was last discussed. But when Wisconsin Athletic Director Barry Alvarez hosted a question-and-answer session with Badgers fans over the weekend, he couldn’t help but talk about the subject.

Alvarez has said before that he’s in favor of expanding the playoff from four teams to eight teams, and B1G commissioner Jim Delany has also talked about have a conversation about expansion. On Saturday, Alvarez backed up his statements, saying that the committee hasn’t done its job appropriately recently.

Mainly, Alvarez is upset that the B1G has been left out each of the last two years and the B1G champion has been omitted the past three seasons.

“I was on the initial committee and I thought four teams in the playoff was good. It was great. It was much better than the two-team playoff decided by computers. Because I wanted to know who’s programming those computers and what are they putting in? I was never satisfied with that. I thought four really helped college football. I thought that would be it,” Alvarez said, in a video recorded by The Athletic. “But when our league is left out of the playoff for three years in a row, I’m not happy with that. I don’t think that we have followed the criteria set by the commissioners in naming those four teams. There’s a way you can go to eight teams very easily, starting a week early with a bye with the top four seeds. You can go to eight teams easily. There are eight teams that really could have a chance to win. So I think it will expand, I just don’t know when.”

The topic of expansion was never quite as heated as last December, when Oklahoma, Ohio State and Georgia all made legitimate arguments to compete for a national championship, but only one spot remained available.

Ultimately, the Sooners got the bid and the B1G was left out of the conversation again. Since then, Alvarez, Delany and Nebraska’s Bill Moos have talked about the possibility of expansion.

Expanding the playoff probably wouldn’t be quite as easy as Alvarez says, but it’s certainly not out of the realm of possibility. If there’s another controversial situation at the end of next season, the discussion could continue to pick up steam.
