Going to Stanford doesn't prevent you from doing stupid things. So we have Cardinal linebacker Shayne Skov, who was arrested and jailed last weekend for driving under the influence.

The Stanford Daily, which first reported the arrest, said Skov "was transported to the San Jose main jail and booked for driving under the influence at 2 a.m. Sunday." He was pulled over in the parking lot of his dormitory.

It will be interesting to see how Stanford handles this. It seems like a serious but isolated incident. Skov is a good student, NFL prospect and a great team leader. If healthy, he likely would rate as the top returning inside linebacker in the Pac-12.

But he's not irreplaceable. Stanford knows this because it played solid defense even after he suffered a season-ending knee injury in the season's third game at Arizona. Skov is still not 100 percent and is not expected to see much action in spring practice.

Of course, with Skov, the Cardinal's 3-4 defense is much better than without him, even with plenty of depth at the position.

"We have an expected standard of excellence and conduct for our players and Shayne failed to adhere to those standards," Stanford coach David Shaw said in a statement released through a team spokesman. "It's a matter we are taking very seriously. Shayne will be responsible to adhere to any legal responsibilities regarding this event along with ramifications which will be determined by the program."

That means the ice under Skov's cleats is thin. The Cardinal open the 2012 season against San Jose State and then play host to Duke. They won't need Skov to win those games, if Shaw opts to suspend him.

But USC comes a-calling in Week 3. Skov's presence would certainly come in handy against Matt Barkley & Co.
