Oregon State, Washington State start Pac-12 rebuild with 4 Mountain West schools

The Beavers and Cougars will welcome Boise State, Colorado State, Air Force and San Diego State to the conference in 2023, as the Pac-12 looks to regain its footing after losing USC and UCLA to the Big Ten.

The addition of these four schools will give the Pac-12 12 members, the minimum number required to hold a championship game. It will also expand the conference's footprint into new markets, including Boise, Colorado Springs, San Diego and Fort Collins.

The Pac-12 has been in a state of flux in recent years, with the departures of USC and UCLA to the Big Ten leaving the conference with just 10 members. The addition of these four schools will help to stabilize the conference and provide it with a more solid foundation for the future.

Boise State is a perennial contender in the Mountain West, having won the conference championship six times since 2006. The Broncos have also played in three Fiesta Bowls and one Orange Bowl during that time.

Colorado State is another strong program from the Mountain West, having won the conference championship twice in the past decade. The Rams have also played in two bowl games during that time.

Air Force is a service academy that has been playing football since 1955. The Falcons have won the Commander-in-Chief's Trophy 20 times, which is awarded to the top-ranked team among the three service academies (Army, Navy and Air Force).

San Diego State is a rising program that has won the Mountain West championship twice in the past five years. The Aztecs have also played in two bowl games during that time.

The addition of these four schools will make the Pac-12 a more competitive conference. The Beavers and Cougars will be looking to challenge for the conference championship in the coming years, and the addition of these four schools will only make that task more difficult.

The Pac-12 is expected to announce the full details of the expansion later this week. The conference is also expected to announce a new television deal, which will help to provide the conference with a more stable financial footing.
