The renowned co-founder of AccuScore enters bowl season on an impressive 16-9 run on his college football picks, and he has had an especially keen eye for the tendencies of BYU.

Now he has evaluated the latest 2018 Famous Idaho Potato Bowl odds and crunched the numbers for every possible scenario for Western Michigan vs. BYU. You can only see his Idaho Potato Bowl picks over at SportsLine.

Oh knows Western Michigan features an explosive offense that can rack up yards and points in a hurry. The Broncos ranked third in the MAC in total yards per game (447.2) and finished the season averaging over 200 rushing yards per contest.

The Broncos are led by All-MAC First-Team running back LeVante Bellamy, who ran the ball 190 times this season for 1,172 yards and seven total touchdowns. Bellamy and the Broncos will be eager to face a BYU defense that was gashed for 162 rushing yards and three touchdowns in its last outing against Utah. 

And Western Michigan has been able to keep pace with high-powered teams all season. The Broncos have only lost by more than 12 three times this season, staying within a point of Ball State and a touchdown of Syracuse in their other losses.

But just because Western Michigan features an explosive offense doesn't mean it can stay within the Potato Bowl spread.

BYU knows what it takes to be successful in a bowl game. The Cougars have appeared in postseason play 13 times in the last 14 years and are 5-3 in their last eight bowl games. And they enter the Idaho Potato Bowl 2018 with one of the nation's stingiest defenses. In fact, the Cougars have held opponents to 21 points or fewer in four of their last five games.

The defense is led senior linebacker Sione Takitaki, who has recorded 99 total tackles this season, which includes double-digit takedowns in four of his last five outings. Brigham Young has covered four straight, beating the spread against Utah, New Mexico State, Massachusetts, and Boise State. They're 7-4 against the spread versus FBS teams this season.

Oh has analyzed this matchup from every possible angle and while we can tell you he's leaning over, he has discovered a crucial x-factor that makes one side of the spread a must-back. He's only sharing what it is, and who to back, at SportsLine.
