Why the Fresno State Bulldogs can cover the spread
Fresno State finished its regular season with two straight victories, including a 31-13 decision over San Jose State last week.
The Bulldogs, having already clinched the MWC West, only led the Spartans 3-0 at the half. But Fresno State scored the first 14 points out of the locker room to take control on its way toward its 10th win of the season.
The Bulldogs outgained San Jose State 515-367 and outrushed the Spartans 198-60. Fresno State has outgained six of its last seven opponents, each by at least 100 yards.
The Bulldogs are also 8-4 ATS on the season and 4-2 ATS on the road.
Why the Boise State Broncos can cover the spread
The Broncos finished their regular season with seven straight victories, including a 33-24 division-clinching decision over Utah State last week.
Boise State spotted the Aggies the first seven points of the game, then scored the next 17 to take a lead it would not relinquish. In the end, up by two, the Broncos delighted their financial backers by tacking on a touchdown with four seconds left to cover the spread as three-point favorites.
Boise State racked up 509 yards of total offense, outrushed Utah State 199-62, held a 38/22 advantage in time of possession and won the turnover battle 2-0.
The Broncos have outgained each of their last three opponents and outrushed their last four foes. They're also 3-0 ATS over their last three games.
Smart betting pick
Boise State won this matchup one month ago 24-17 but had to rally from a 17-3 deficit to do it. Also, Fresno State owns the better performance this season against common opponents. And while the Broncos own the edge on offense, the Bulldogs own the edge on defense.
The smart money here likes Fresno State.
