Much like the NFL this week, college football features some major mismatches with big point spreads favoring very public teams. That means sportsbooks obviously will need the underdogs in those Week 4 games to keep the scores closer than expected and cover in hopes of beating bettors and turning a profit.

For example, the Ohio State Buckeyes are coming off a 38-7 win over the Army Black Knights last Saturday following a surprising 31-16 home loss to the Oklahoma Sooners the previous week. The Buckeyes failed to cover both of those games and needed to rally late to beat the number in their season-opening 49-21 road victory against the Indiana Hoosiers.

Ohio State is listed as a 40-point home favorite this Saturday versus the UNLV Rebels, who are coming off a bye week after routing the Idaho Vandals 44-16 as 5-point road dogs. But the Rebels lost their season opener 43-40 to the Howard Bison as 45.5-point home favorites, so who knows which UNLV team will show up.
