Purdue at NevadaThe Boilermakers are a popular breakout team pick in the Big Ten this season, as Purdue boasts arguably the conference’s most-entertaining player in Rondale Moore.Road games are never easy, though, especially to start the season.Purdue enters this contest as a 10.5 point-favorite.

Stanford vs. NorthwesternThis one could be one of the best games of Week 1, pitting two Power 5 teams against each other.Stanford enters this contest as a touchdown favorite, though Northwestern has what it takes to pull off the upset.The Cardinal will look to avoid losing to the Wildcats like they did a couple of seasons ago.

Utah at BYUUtah enters the 2019 college football season as a darkhorse College Football Playoff team, with several analysts picking the Utes to win the Pac-12 and find a way into the national championship race.The Pac-12 contenders should start the season with a nice win, though this is a big rivalry game, and BYU will come out looking to pull off the big upset.It’s a night game, too, so the crowd at BYU should be rocking.

Oklahoma vs. HoustonThe Sooners will be starting Jalen Hurts at quarterback in 2019, looking to make another run at a Big 12 championship and a College Football Playoff berth.Houston, meanwhile, is now led by former West Virginia head coach Dana Holgorsen.Can the Cougars shock the college football world with a huge Week 1 upset?

Notre Dame at LouisvilleThe Fighting Irish enter the 2019 college football season as a top 10 team with national championship hopes.Notre Dame comes into this game against Louisville as a 20-point favorite, but this is a road night game, and you never know what can happen in Week 1.This should be an easy win for Brian Kelly’s team, but if the Fighting Irish start slow, this could be interesting.
