Lyle Sendlein and Ted Larsen are gone. And while A.Q. Shipley remains and the Cardinals have signed a couple of other street free agents in Taylor Boggs and Valerian Ume-Ezeoke, it's pretty clear the Cardinals are on course to draft a center at some point. Maybe it's the first round, a guy like Alabama's Ryan Kelly (who has been a favorite for mock drafters to scribble next to the Cardinals at 29th overall.) But it won't be a surprise, even though the Cards don't have a second-round pick, if they wait. After listening to both Steve Keim and Bruce Arians Tuesday, it shouldn't even be a surprise if one comes later -- and isn't even technically a center. Not yet.

"In this draft, there are several opportunities to draft centers in all rounds," Keim said. "Some of those guys are projections. There are some guys in the second, third, fourth rounds, who are going to be guys who played left tackle or they played guard at the collegiate level, who we worked out at center or they played center previously in their career that we think has the skill set. There are going to be opportunities to address that position if we feel necessary."

Arians noted a couple of very good NFL centers like Jeff Hartings of the Steelers and Tim Grunhard of the Chiefs (Grunhard played guard in college, Hartings started his NFL career at guard before moving to center) that made the move. "When you say a college center, there might be three college centers, but there are 15 potential centers," Arians said.

Options obviously open up a lot of possibilities for that first pick. Waiting on a center makes it easier to take a cornerback. Or a defensive lineman. Whatever Keim might want.
