Now, he has turned his attention to Week 13 and is sharing his most confident college football expert picks over at SportsLine. Get his college football picks now. We can tell you Sallee is backing Michigan (-9) to cover the spread in a Big Ten battle at Indiana

Michigan boasts one of the nation's top defenses, giving up an average of 16.4 points and 261.6 yards per game this season. However, the Wolverines will be challenged by an Indiana offense that is averaging 33.3 points of its own.

But Sallee believes the x-factor in this matchup will be the play of Wolverines quarterback Shea Patterson. In Michigan's 44-10 victory over Michigan State last Saturday, Patterson completed 24-of-33 pass attempts for 384 yards and four touchdowns. He's also proven to be a lethal threat with his legs throughout the season, having scored five rushing touchdowns in his last seven games.

Plus, Michigan has dominated this series over the years. In fact, the Wolverines have won 10 straight meetings against the Hoosiers and are 8-0 in their last eight road games at Indiana. Confidently lock in the Wolverines as one of your top Week 13 college football picks because Sallee believes Patterson is due for another big game on Saturday. 

Sallee has also found two other college football picks he's high on, including a must-see underdog he likes to win outright in Week 13. You can only see who he's backing at SportsLine.
