Four keys and a pick: No. 4 Michigan vs. Michigan State preview

The Michigan-Michigan State football game is on Saturday at 7:30 p.m. ET. The game pits the undefeated fourth-ranked Wolverines against the scrapping Michigan State team. 247Sports' Zach Shaw gives his four keys for Michigan and a score prediction for the game.

Payton Thorne's 16.7 percent of his pass attempts this season have been 20 or more yards downfield. This is more than anyone Michigan has faced this year. Thornes has not always been efficient on down-field throws, but 10 of 11 of the quarterback's touchdowns have come on intermediate or deep throws.
