Utah and BYU are back together again!

In what just came official, Utah, Arizona and Arizona State will be the newest members of the Big 12 Conference, joining Colorado which accepted an invite last week.

In a span of 24 hours, the Pac-12 Conference aka “The Conference of Champions” is left for dead with just Stanford, Cal, Washington State and Oregon State remaining. Buyouts for schools like San Diego State would be too steep, so the most likely scenarios for those four schools is either merging with the Mountain West Conference (MWC), the Atlantic Coast Conference (ACC), or going Independent. Meanwhile, Oregon and Washington are joining up with UCLA and USC to go to the Big 10 next year.

Barring any unexpected setbacks, the 16-team Big 12 will be comprised of:

Arizona State
Iowa State
Kansas State
Oklahoma State
Texas Tech
West Virginia

This would put the conference at the same size as the SEC and two smaller than the 18-team Big Ten. The ACC has 14 full-time football members, however, with rumors of Clemson and Florida State looking to leave — not to mention Notre Dame still independent — there are still plenty of more dominos to fall in what has been unprecedented day in college athletics.

With BYU and Utah reunited, the Holy War is officially back. No more non-conference games, the Utes and Cougars will be playing during Thanksgiving weekend during ‘rivalry week’ — one of the few rivalries left in college athletics through all the conference realignment mess over the past decade.

With Utah in the Big 12, here’s how BYU, Utah and national pundits reacted to conference expansion news:

With 16 teams, the Big 12 has positioned itself to be part of the ‘Significant 3’ behind the Big 10 and SEC.
