One of the important parts of the end-of-preseason roster choices will be how the Cardinals choose to divvy up their offensive line spots. As of now we have the five starters -- from left tackle across, it'll be Jared Veldheer, Mike Iupati, A.Q. Shipley, Evan Mathis and D.J. Humphries. Beyond that, you figure they keep fourth-round center Evan Boehm and Swiss Army knife lineman Earl Watford, who is still recovering from a knee injury. Does rookie guard Cole Toner stick? Guard Antoine McClain? Tackle John Wetzel? Do they add a guy?

Watford started two games at right tackle last year and is a strong possibility to play there if Humphries goes down. For now, coach Bruce Arians made it a little more clear how they would handle the backup tackle situation on the left. If Veldheer got hurt, Arians said, the move would likely be to switch Humphries -- who spent his college days as a left tackle -- back over to the left, and then fill in the right.

Arians also had a good line about what the Cardinals ask their offensive tackles to do.

"Block the best players on the other team," Arians said. "That's pretty much it. those defensive ends get paid a bunch of money. They get paid a million dollars a sack, you get paid half-a-million for 59 good blocks."
