A lot can change in one week of college football!

What a weekend that was for the B1G in Week 7! Nebraska, seeking its first one of the season, somehow found a way to squander a 10-point lead in an OT loss to Northwestern. Penn State also finished the week on a sour note, getting upset by Michigan State in Happy Valley.

On the flip side of things, Michigan looked impressive while rolling over Wisconsin in Ann Arbor. And though it took a while to put away another big underdog, Ohio State kept its undefeated season going with a win over Minnesota.

Things are shaping up for a great second half of the season, and it all starts with the action in Week 8. With that in mind, here are the betting lines for every B1G game, courtesy of Vegas Insider:

Iowa: -12 over Maryland

Northwestern: -21 over Rutgers

Michigan: -6.5 over Michigan State

Ohio State: -13.5 over Purdue

Penn State: -14 over Indiana
