Halftime update: Michigan State-Michigan

ANN ARBOR, Mich. -- Some quick thoughts at the half from Michigan Stadium, where No. 17 Michigan State leads No. 18 Michigan 17-10.

Turning point: Michigan led 10-7 and forced Michigan State into a third-and-15 deep in its own territory. But Kirk Cousins hit Keshawn Martin on a crossing route that went for 17 yards and a first down. Four plays later, Le'Veon Bell rumbled 41 yards to the end zone to give the Spartans a 13-10 lead.

Stat of the half: The Wolverines racked up 263 yards and held the ball for more than 16 minutes but reached the end zone only one time. Michigan entered the game having scored a Big Ten-leading 29 touchdowns.

What Michigan State needs to do: Keep avoiding the major mistake on offense and make sure Denard Robinson doesn't break free. Robinson is making plays here and there, but he hasn't busted a big gain yet today. The Spartans are the ones making the biggest plays on offense, and they have to continue to limit major mistakes.

What Michigan needs to do: The Wolverines have to convert drives into points. They're moving the ball nicely and mixing things up, but they can't keep crossing the midfield stripe and settling for field goal attempts or nothing. I like the sustained drives, but Michigan could use one of those 80-yard plays early in the second half. Michigan also must do a better job of pursuing Spartans ball carriers. A lot of bad angles.
