The Cardinals got back to work Monday. People noted, understandably, that quarterback Josh Rosen was indeed on hand. But the news that was important from Monday came on the other side of the ball with Rodney Gunter returning for another season.

The defensive line needed the depth. Gunter went into free agency looking to test the waters, but nearly a month into it, he apparently didn't see the long-term deal materialize for which he had hoped. So he comes back to the Cardinals on a one-year deal, with the potential for free agency again next season but for now as a probable starter in the 3-4 scheme at defensive end with Corey Peters at nose tackle and newly signed Darius Philon as the other end. Peters was clearly happy, as he noted on Twitter.

Gunter's signing, especially with it being a one-year deal, does not preclude the Cardinals from taking a defensive lineman (such as Quinnen Williams) early. The defensive line is still a place where the Cards will likely try to address at some point in the draft. The timeline of Robert Nkemdiche's return from an ACL tear remains a question. The Cards still need to find out if anyone else on the roster can help. The fact the Cards are going to the 3-4 (and, when they use four down linemen in passing situations, they'll have guys like Chandler Jones and Terrell Suggs playing ends) helps because the Cards will only need five or six defensive linemen on game days. Gunter helps that number already.
