Luck is having a big day

Posted by ESPN.com's Ted Miller

TUCSON, Ariz. -- Arizona can't Stanford.

At the end of three quarters, the Cardinal has piled up 469 yards. It leads 38-29 with the ball on the Wildcats 33 to start the fourth.

Toby Gerhart has 115 yards and two touchdowns, and he'll likely pile up some big numbers as Stanford protects its lead in the fourth.

But the story is Andrew Luck.

He's completed 15 of 20 for 337 yards with three TDs. That's 16. 3 yards per completion.

Oh, and he's a redshirt freshman.

Pac-10 has some good young QBs, eh?
