Halftime report: Stanford 28, Arizona 20

Posted by ESPN.com's Ted Miller

TUCSON, Ariz. -- Hey, Arizona loves replay now!

Replay turned an interception from Stanford cornerback Kris Evans into a trap, and allowed Arizona to finish an 89-yard drive with a touchdown, which narrowed the Cardinal's halftime lead to 28-20.

Stat of the half: Just one number: 314. That's Stanford's total yardage against a defense that gives up 282 yards per game.

Best player in the half: Stanford quarterback Andrew Luck threw a pick-six on his first possession, but that was about his only mistake. He completed 12 of 17 for 231 yards and three touchdowns in the first half.

Best call: That replay, which corrected an incorrect on-field call. It looked like Nick Foles, on first down from Stanford's 16, had thrown an interception. But the ball, deflected at the line of scrimmage, was trapped by Evans. Last week at Washington, replay was not as generous to the Wildcats.

What Arizona needs to do; What Stanford needs to do: It's simple for Arizona. It needs to find a way to slow down Stanford's offense, which can beat you on the ground with Toby Gerhart or through the air with Luck. The Wildcats might want to cover the Stanford tight end, see that Jim Dray and Konrad Reuland combined for four receptions for 100 yards. As for Stanford, it can't let up. It mostly dominated the first half but, because of that pick-six from Robert Golden, it only leads by eight.
