Halftime instant analysis: Bama 31, U-M 7

ARLINGTON, Texas -- No. 2 Alabama showed none of the signs of championship fatigue against No. 8 Michigan in the first half, jumping out to a 31-7 lead.

The Crimson Tide scored on four straight series after starting the game with a three-and-out.

Stat of the half: Michigan made it look better with a late touchdown in the second quarter, but Denard Robinson's day under center has not gone well so far. The senior quarterback had allowed more interception yards than total passing yards before a 71-yard pass that set up the Wolverines' lone score.

Player of the half: Alabama cornerback Dee Milliner didn't let a pass by him against Michigan, intercepting one and batting down three more.

What's working for Alabama: The offensive line has had no trouble with the Wolverines. They've cleared the way for 139 yards rushing and given AJ McCarron enough time to compose a sonnet every time he drops back.

What's not working for Alabama: Getting nitpicky, but Alabama isn't winning the penalty battle the way coach Nick Saban would like. The Tide have committed five penalties for 35 yards.
