Remember the San Diego State team that won back-to-back games over Pac-12 opponents Arizona State and then-No. 19 Stanford in September?

Fresno State completely dominated it Saturday night in San Diego, rolling to a 27-3 win to all but clinch the Mountain West’s West Division title with four conference games still to play.

The Bulldogs (5-2, 4-0 MW), who were 1-11 a year ago, are now the team to beat in the Mountain West and at the top of our weekly power rankings.

Boise State (5-2, 3-0) moves up to No. 2 this week after picking up a big win at home Saturday night over Wyoming. CSU (6-2, 4-0) still holds a half-game lead on the Broncos in the race for the Mountain Division title but looks a lot more vulnerable than it did two weeks ago after squeaking past also-rans Nevada and New Mexico the past two weeks.

Here’s a complete look at this week’s MW power rankings:

1. Fresno State (5-2, 4-0 MW)

Jordan Mims ran for 112 yards on 21 carries and Josh Hokit ran for 77 yards and three touchdowns on 14 carries to lead the Bulldogs at San Diego State. Fresno State’s defense limited San Diego State running back Rashaad Penny to 69 yards — 80 below his average of 149.4 through the first seven games of the season. The Bulldogs have tough games left against Mountain Division foes Boise State and Wyoming, but they could probably lose both and still win the West Division title.

2. Boise State (5-2, 3-0 MW)

The Broncos scored touchdowns on their first three possessions of the second half Saturday night to beat visiting Wyoming 24-14. The Boise State defense limited Wyoming quarterback Josh Allen to 131 passing yards on 12-of-27 passing, intercepted him twice and sacked him four times. Backup QB Montell Cozart had a hand in all three Boise State touchdowns, running for two and passing for the third.

3. CSU (6-2, 4-0 MW)

For the second week in a row, the Rams were less than impressive but still found a way to win. This week, Colorado State University needed a late 52-yard field goal by Wyatt Bryan and fourth-down sack on the game’s final play to hold off New Mexico 27-24 in Albuquerque. Izzy Matthews ran for 116 yards and one touchdown and quarterback Nick Stevens threw for 231 yards and two TDs to lead the Rams to their fourth straight win and first 4-0 start in league play since 2002.

4. San Diego State (6-2, 2-2 MW)

The Aztecs have dropped two straight games — to Boise State and Fresno State — following a 6-0 start to the season that earned them a spot in the Top 25 for three weeks. Penny has been held to 53 and 69 rushing yards the past two weeks after gaining 107 or more in the first six games. The Aztecs, who looked like a shoo-in for the West Division title three weeks ago, now need to win out and get some help from teams facing Fresno State to claim it.

5. Wyoming (4-3, 2-1 MW)

The Cowboys had a three-game winning streak snapped with their loss in a back-and-forth game at Boise State. Wyoming’s offense was held to 242 yards by the Broncos. Quarterback Josh Allen struggled in the passing game and had no help in the run game. Allen was the Cowboys’ leading rusher with 62 yards and a touchdown on 18 carries.

6. Utah State (4-4, 2-2 MW)

The Aggies bounced back from back-to-back losses at home to CSU and Wyoming with a 52-28 win at UNLV Saturday. LaJuan Hunt ran for 101 yards and three touchdowns and Jordan Love, a redshirt freshman making his first career start, threw for 316 yards and two TDs for Utah State. The Aggies intercepted two passes and recovered a fumble to regain a share of the national lead in takeaways with 20.

7. Air Force (3-4, 2-2 MW)

The Falcons had three 100-yard rushers — Tim McVey (139), Ronald Cleveland (118) and Taven Birdown (101) — and 550 yards on the ground Friday night in a 45-42 win at Nevada. Luke Strebel’s 30-yard field goal on the final play provided the winning margin for the Falcons, who lead the MW in scoring at 37.3 points per game.

8. New Mexico (3-4, 1-3 MW)

Tyrone Owens ran for 159 yards and a touchdown to lead a 318-yard rushing attack by the Lobos on Friday night in their loss to CSU. A touchdown pass from backup QB Tekava Tuioti to Arron Molina with 24 seconds left, followed by an onside kick recovery, gave the Lobos a chance to win right up until the very end, when Tuioti was sacked by CSU linebacker Evan Colorito on the final play.

9. Nevada (1-7, 1-3 MW)

The Wolf Pack lost a close game for the second straight week and third time this season, losing by three at home to Air Force a week after a 44-42 loss at CSU. Quarterback Ty Gangi threw for 239 yards and two touchdowns and Kelton Moore ran for 101 yards and one TD for Nevada.

10. Hawaii (3-4, 1-3 MW)

The Rainbow Warriors had a bye this past weekend but hope to carry the momentum they gained in a 37-26 win at home Oct. 14 over San Jose State into this Saturday’s matchup with reeling San Diego State at Aloha Stadium. Hawaii had lost four straight games prior to the win over San Jose State.

11. UNLV (2-5, 1-3 MW)

After matching visiting Air Force touchdown for touchdown in the first half, which ended in a 28-28 tie, UNLV allowed 24 unanswered points in the second half Friday night while dropping its third straight game and falling to 9-22 overall and 6-14 in the MW under third-year coach Tony Sanchez.

12. San Jose State (1-7, 0-4 MW)

San Jose State avoided another loss last weekend, but only because the Spartans didn’t play a game. Their only win under first-year coach Brent Brennan was a 34-13 victory Sept. 2 over Cal Poly of the lower-tier Football Championship Subdivision.
