Top college football predictions for Week 9

One of the top college football picks Marshall is recommending for Week 9: No. 10 Penn State (-31) covers against Indiana in a noon ET Big Ten on CBS matchup at Beaver Stadium.

Indiana has yet to beat a Power 5 team this season, and it has only picked up one win in its last 11 road games. The Hoosiers are winless in their last 11 road games at Penn State, and they have lost their last three games this season by at least 17 points. They were only 6-point underdogs in their 31-14 loss to Rutgers last week, giving up 276 rushing yards to the Scarlet Knights.

Penn State won its first six games of the season by at least 17 points before suffering a one-score loss at No. 3 Ohio State last week. The Nittany Lions have covered the spread in seven of their last eight games dating back to last season, and they are riding a six-game home winning streak. They are primed for another blowout win on Saturday, as these teams have been trending in opposite directions this season. See which other picks to make here.
