NorthwesternBoston College What you need to know: Northwestern is seeking a 3-0 start for the third time in five years. It was Game 3 last season where the Wildcats’ season was derailed and began a five-game losing streak. The Wildcats are undefeated this season, but it has taken some fourth-quarter magic to get them there. They snuck by Syracuse with a last-second touchdown to win by one point in the opening week and scored 17 points in the fourth quarter to defeat Vanderbilt 23-13 last week. Northwestern will be looking to get more out of their two quarterbacks this week. Trevor Siemian and Kain Colter combined for 133 yards passing last week. Boston College quarterback Chase Rettig has already thrown for 660 yards and five touchdowns this year. The Eagles lost to Miami to start the season and defeated Maine last week.

Scott Powers’ prediction: Northwestern 31, Boston College 28

IllinoisCharleston SouthernWhat you need to know: Illinois should be able to cruise this week over FCS opponent Charleston Southern after the Illini were knocked down in last week’s 45-14 loss to Arizona State. Illinois was without quarterback Nathan Scheelhaase due to injury last week, and he is expected to play this week. The offense struggled last week without him. Reilly O'Toole and Miles Osei combined for 101 passing yards, one touchdown and three interceptions. The one positive for Illinois last week was Josh Ferguson's 101 rushing yards. Charleston Southern comes to Champaign following lopsided losses to the Citadel and Jacksonville.

Powers’ prediction: Illinois 55, Charleston Southern 6

ArmyNorthern Illinois<What you need to know: Northern Illinois bounced back from its season-opening loss to Iowa with an easy win over Tennessee-Martin last week. Northern Illinois has a chance to roll against Army, too. The Huskies had no trouble scoring against Army last season in a 49-26 win, and Army’s defense showed in last week’s 42-7 loss to San Diego State it still has its deficiencies. Northern Illinois quarterback Jordan Lynch was sharp last week, completing 19-of-25 passes for 214 yards and a touchdown. He also ran for three scores. Safety Jimmie Ward was the MAC West Defensive Player of the Week after recording 10 tackles, two pass break-ups and one interception last week.

Powers’ prediction: Northern Illinois 45, Army 20
