TUCSON, Ariz. -- Stanford leads Arizona 16-10 at the half.
Best player: It was linebacker Shayne Skov until he was hurt in the second quarter. Kicker Jordan Williamson has been fantastic, converting field goals of 20, 33 and a career-long 45. He's also had more depth on his kickoffs.
Best call: Without a doubt, the fourth-and-1 call at the Arizona 24-yard line. A misdirection pitch that forced the defensive end to bite on the initial pitch. Anthony Wilkerson took the flip on the backside and then scampered 24 yards for the score.
What Stanford needs to do: Stay balanced. The Cardinal are running the ball well. The loss of Skov -- who was carted off from the sidelines -- is a big one. They can't let that emotionally deflate them. Same with tight end Coby Fleener on offense, who hasn't returned since taking a big shot in the first quarter. His return for the second half is unknown. He has been walking the sidelines, but without his helmet.
What Arizona needs to do: Fortunately for them, Andrew Luck isn't playing a great game. Running the ball doesn't appear to be an option, which was predictable. Nick Foles is proving to be as accurate a quarterback as expected. Their best chance is to stay in the air. There is great risk being a pass-only team. But with that comes great reward.
