TEMPE, Ariz. – It’s time to move on from Jerraud Powers.

The former Arizona Cardinals cornerback signed a one-year deal with the Baltimore Ravens on Friday, officially taking him off the free-agent market and out of the rotation of possible solutions for Arizona at cornerback.

So where does this leave the Cardinals? They’re still looking for Powers’ replacement.

Arizona has 10 potential replacements currently on its roster, including Powers’ likely successor as a starter, Justin Bethel. The Cardinals also drafted two cornerbacks in this year’s draft, Brandon Williams and Harlan Miller, and have two practice-squad corners from last season on the roster as well.

But none can instantly fill Powers’ role as well as he did.

Bethel showed some progress as a transitional cornerback in the final two weeks of the season and the playoffs when he replaced Powers, who moved to the slot inside to take over Tyrann Mathieu’s role after Mathieu’s ACL injury in Week 15, but it was minimal. Bethel’s inexperience shined brightly. After playing corner sparingly in college, Bethel’s only true exposure to the position came last season, in his fourth NFL season. Green Bay Packers quarterback Aaron Rodgers picked on him repeatedly in Week 16, drawing a blueprint for how quarterbacks should approach Bethel.

Any growth Bethel made last year at corner was stunted when he had foot surgery in April. He’ll be able to prepare for the classroom part of being a corner, but transporting that to the field will have to wait until training camp. That leaves Arizona in a vulnerable position.

If the Cardinals don’t sign or trade for a veteran cornerback before the season, they’ll be left with a slew of inexperienced corners on a side of the field that will be targeted quite a bit because no quarterback wants to throw at All-Pro Patrick Peterson.

Bethel and Arizona’s two draft picks are still projects. The other six corners are unproven.

Bethel is capable of being a starter, but until he can grasp the intricacies of a complex position, he’ll be a weakness for a Cardinals’ defense that can’t afford one on its way to Super Bowl LI.
