San Diego State moves to the top of the Mountain West power ranking this week after a dominating performance Saturday night at Arizona State.

Boise State, which led the rankings last week, lost its position after blowing a 31-10 fourth-quarter lead and losing in three overtimes at then-No. 22 Washington State.

1. San Diego State (2-0)

Rashaad Penny is quickly making Aztecs’ fans forget all-time NCAA rushing leader Donnel Pumphrey. Penny ran for 216 yards and one touchdown, returned a kickoff 99 yards for another TD and also caught a touchdown pass Saturday night in San Diego State’s 30-20 win at Arizona State. The Aztecs scored first and never trailed

2. Boise State (1-1)

The Broncos could have stayed on top this week had they won a game it appeared they couldn’t lose while leading by 21 points early in the fourth quarter. But they did, thanks in large part to an ill-advised pass by backup quarterback Montell Cozart that a Washington State defender returned 36 yards for a touchdown with 5:51 remaining to cut the Broncos’ lead to 31-24. Cozart replaced starting quarterback Brett Rypien who was injured after two big hits late in the first quarter.

3. CSU (2-1)

The Rams did what they were supposed to do against a Football Championship Subdivision team, dominating Abilene Christian on both sides of the ball in a 38-10 win Saturday. The real test of what the Rams, who went 1-1 against Pac-12 teams Oregon State and Colorado in their first two games, are made up comes this weekend at top-ranked Alabama.

4. Wyoming (1-1)

Like CSU, the Cowboys also took care of business against an FCS foe, beating Gardner-Webb 27-0, a week after opening the season with a 24-3 loss at Iowa. Quarterback Josh Allen threw for 328 yards and two touchdowns, and the Wyoming defense allowed just 195 yards.

5. Air Force (1-0)

The Falcons rolled to a 62-0 win Sept. 2 over Virginia Military Institute and had this past weekend off. So it’s hard to get a good feel yet for Air Force. That will come Saturday, when the Falcons travel to No. 7 Michigan.

6. Utah State (1-1)

Quarterback Kent Myers was nearly perfect, completing 24 of 26 passes for 323 yards and two touchdowns with one interception in the Aggies’ 56-13 dismantling of FCS opponent Idaho State on Thursday night. Myers also ran for 85 yards and two touchdowns to help Utah State bounce back from a 59-10 loss Sept. 1 at then-No. 10 Wisconsin

7. Fresno State (1-1)

There’s no shame in getting whipped on the road at top-ranked Alabama, as was the case for the Bulldogs on Saturday in a 41-10 loss. Alabama led 28-3 at halftime and was never threated by a Fresno State team that opened its season under new coach Jeff Tedford a week earlier with a 66-0 win over FCS foe Incarnate Word.

8. Hawaii (2-1)

After opening the season with wins at Massachusetts and at home against Western Carolina, the Rainbow Warriors were brought back to reality Saturday night in a 56-23 loss at UCLA. Hawaii was down 42-7 early in the third quarter but picked up some points late against UCLA reserves.

9. Nevada (0-2)

The Wolf Pack fell behind 20-3 early to visiting Toledo on Saturday and never recovered, losing 37-24 to the Mid-American Conference school. Nevada, which opened a week earlier with a 31-20 loss at Northwestern, couldn’t get its running game going against Toledo and wasn’t good enough through the air to overcome it, with quarterback Ty Gangi completing just 19 of 37 passes for 277 yards and two touchdowns.

10. New Mexico (1-1)

After falling behind 30-5 to visiting New Mexico State late in the third quarter Saturday night, the Lobos made a furious comeback bid by scoring 23 points in the final 13 minutes. After leading the country in rushing yards last season at 364.1 yards a game, New Mexico is averaging just 217.5 through two games in 2017.

11. San Jose State (1-2)

Nobody really expected San Jose State to go into Austin on Saturday and beat Texas. But the Spartans weren’t even competitive. They were limited to 171 yards of offense while losing 56-0.

12. UNLV (1-1)

The Rebels bounced back nicely from an embarrassing 43-40 loss at home to Howard, an FCS team coming off a 2-9 season, with a 44-16 win at Idaho. Still, the loss to Howard is going to sting for quite some time.
