Morning links: A longer look at the defensive line

There was no practice to report on yesterday. But our series of position previews continues.

Our preview of the Washington State defensive line is in today’s paper . On the blog yesterday we had notes about how the poor air quality in Pullman is affecting the Cougars, and about a cornerback recruit who says he will sign with WSU.

And tomorrow at 11 a.m. we’ll hold our weekly live chat.

Here are a few links from around the Pac-12:

— Arizona State running backs coach Bo Graham, son of head coach Todd Graham, resigned yesterday .

— Joe Dahl was named to the Pac-12 Blog’s preseason All-Conference team .

— Christian Caple ponders which true freshmen could play at Washington.

— Oregon’s talented quarterbacks could still split reps .

— The Beavers are also enamored of two QBs.

— Players are still auditioning for the spots next to Scooby Wright.
