BOISE, Idaho(AP) -- Boise State coach Chris Petersen simply
refuses to get into the campaign business.

After his sixth-ranked Broncos rolled over New Mexico State 42-7
Saturday to finish 13-0 and go undefeated for the second
straight season, Petersen resisted any urge he might have had to
argue that the Broncos deserve an invitation to the Bowl
Championship Series.

"I think our record speaks for itself," said Petersen, whose
team went 12-0 last year only to be left out of college
football's big-money bowl games. "We have faith in this system
and think that it should work out it. I don't know why I think
it will work. I just have a feeling it should work out like it
should this year."

Broncos safety Jeron Johnson wasn't nearly as subtle, showing up
at the postgame press conference sporting a sombrero. Some
analysts have pegged the Broncos for a trip to the Fiesta Bowl.
But that hinges on several factors, including Texas beating
Nebraska in the Big 12 title game Saturday night.

"It's something I would like to happen, but we have to wait and
see what happens," said Johnson, who with the rest of Broncos
will have to wait until Sunday night to find out their
postseason destination.

The victory over the lowly Aggies (3-10, 1-7) gave Boise State
the outright WAC title for the second straight year. The Broncos
have dominated the WAC this decade, winning seven of the last
eight titles, including the 2005 title it shared with Nevada.
The Boise State has now won 26 straight regular-season games and
55 straight regular-season home games.

Doug Martin led the way with four touchdowns, and the defense
held New Mexico State to 49 yards passing and 191 total yards.

Kellen Moore, the nation's most efficient passer, was 19 of 30
for 272 yards before leaving in the third quarter with a 35-0
lead. Moore's lone touchdown pass, a 47-yarder to Titus Young in
the first quarter, gave him 39 on the year, a school record.

Fans, who chanted "BCS, BCS, BCS" in the fourth quarter, stormed
the field after time ran out, turning Boise State's iconic blue
turf into a sea of orange and blue as they celebrated with
players and coaches.

After finishing 12-0 last season and being left out of the BCS
mix, Boise State settled for a matchup with TCU in the
Poinsettia Bowl.

But the Broncos have some big wins this year to help their case,
including a 19-8 victory over No. 7 Oregon in the season opener,
and a 44-33 victory last week over Nevada, which had won eight
straight. The Broncos came into the game with the nation's
second-highest scoring offense, averaging 44.3 points per game,
and ninth in total offense, averaging 453 yards per game.

"I think we deserve a chance at the BCS this year," safety
George Iloka said. "We can't do anything about it. I'm not going
to lie - it would hurt if we don't make it this year."

The Aggies were on the verge of getting shutout by the Broncos
for the third straight time, but scored late in the fourth
quarter after Broncos backup quarterback Mike Coughlin fumbled a
snap deep in Boise State territory. Backup Aggies quarterback
Trevor Walls, who replaced injured starter Jeff Fleming, scored
several plays later on a 1-yard touchdown to avoid the shutout.

Aggies running back Seth Smith was the lone bright spot, rushing
for 114 yards on 35 carries. Smith, a junior, finished the
season with 1,016 yards rushing, becoming the first Aggies
running back to surpass the 1,000-yard mark since 2000 and
fourth in school history.

"I think it's big for him and big for our program to be able to
do that with the offense," said first-year coach DeWayne Walker,
whose team has lost 10 straight to the Broncos. "We struggled
this season offensively and for him to be able to get to that
milestone, it says a lot about him and has a lot to say where we
are headed."

Martin had two 4-yard TD runs and Jeremy Avery ran 9 yards for
another score as Boise State reached the end zone three times in
the second quarter to take a 28-0 lead. Martin tacked on a
2-yard touchdown run and a 56-yard score in the third.

Avery had 16 carries for 86 yards and Martin finished with eight
for 83 as Boise State finished with 288 yards on the ground.
Young led Boise State receivers with seven catches for 92 yards.
