Are You Ready For Some Big Lines?

I'm a bit surly sitting here off a 2-4 week which brings my total to 25-29, 1-17 on parlays. There are some big lines out there and it's time to wrestle with them. Odds from USA Today's Opening Line:

Notre Dame -23 1/2 v. Navy
Wisconsin -2 1/2 v. Iowa
Illinois +23 @ Purdue

Giants -10 v. Vikes
Steelers -8 v. Browns
Texans +17 1/2 @ Colts
