What you need to know

The Arizona Cardinals will be looking for their long-term quarterback as one of the many teams in need of a signal-caller for the 2018 season after the retirement of Carson Palmer. Arizona will also have to look at securing either some of their own aging veterans on the defensive side of the ball, or looking to the free agent pool to bolster depth across a multitude of positions this offseason.

Must re-sign

Xavier Williams, DI, 80.8 overall grade

This one is simple, and most likely to actually happen. Williams is a restricted free agent, so in all likelihood by the time free agency opens, he’ll still be a member of the Cardinals franchise, and it would make sense. Rucker is 34 years old and himself an unrestricted free agent and the Cardinals are still trying to figure out life without Calais Campbell on the interior of their defense. With the potential of Williams re-signing, they would bring back the league’s leader in run-stop percentage among defensive tackles as he hauled down 16 run-stops on 110 snaps in run defense in 2017.

Dream splash signing

Patrick Robinson, CB, Philadelphia Eagles, 90.7 overall grade

Robinson would provide an immediate upgrade in Arizona, even over Tramon Williams, who is an unrestricted free agent himself, and 35 years old. Robinson had a breakout year in 2017, capped by his pick-six in the NFC Championship game and subsequent trip to Super Bowl LII. He showed capable of manning up with receivers in the slot as he allowed the league’s fifth-lowest passer rating in slot coverage this season and overall on the season, he recorded five interceptions and another 11 pass breakups, including playoffs. One way or another, Arizona needs to address their secondary, and Robinson’s versatility at the cornerback position would be a great fit.

2018 free agent prospects

Nate Solder, T, New England Patriots

The 30-year-old Solder has long been Tom Brady’s blindside protector, but the time for him to move on from New England may be looming near. For the Cardinals, their offensive line was in shambles most of the year, so a player with Solder’s experience would be an immediate boost.

Andrew Norwell, G, Carolina Panthers

Who won’t be in the Andrew Norwell sweepstakes come this free agent period? Arizona proves a team that is in dire need of a guard, and good guard play at that. Three different guards qualified for a ranking among our season grades, and neither of them graded out higher than a 46.2, nor ranked higher than 46th at the position. Norwell was the league’s third-highest-graded guard and saw the league’s top pass-blocking grade among guards, immediately filling big-time needs for the Cardinals.

Sammy Watkins, WR, Los Angeles Rams

Watkins moved from Buffalo out west to Los Angeles prior to Week 1 of the 2017 season, so a slight move to Arizona would make sense for the 26-year-old speedster. What receiver wouldn’t want to learn from future Hall of Famer in Larry Fitzgerald, who once again proved age is just a number with his 85.3 overall grade this year, or ninth-best in the league. Whether Fitzgerald returns or not next season remains to be seen, and regardless, Watkins and Fitzgerald would make a formidable duo, or Watkins learning while filling Fitz’ shoes makes sense.
