The Arizona Cardinals are one of the NFL’s most intriguing teams as we inch closer to the start of the 2020 regular season. Coming off a 5-10-1 campaign, there is a ton of hype surrounding the young team, and rightfully so as quarterback Kyler Murray excelled as a rookie despite playing behind woeful pass protection. 

The former No. 1 overall pick completed over 64% of his passes for 3,722 yards and 20 touchdowns compared to 12 interceptions, winning the Offensive Rookie of the Year award in the process. Following the addition of All-Pro wide receiver DeAndre Hopkins, who came over via trade back in March, it’s widely expected that Murray takes a big leap as an NFL sophomore. 

With that being said, the Cardinals have a lot of upgrading to do on both sides of the ball, particularly on defense. The Hopkins contract did eat into their salary cap space — $13.5 million to be exact — but Arizona is still projected to be the eighth wealthiest team in the league next offseason with $23.21 million at its disposal, according to Spotrac. 

That should be enough for general manager Steve Keim to make a handful of necessary upgrades. With that in mind, let’s highlight a few impending free agents the Cardinals should absolutely be keeping an eye on this season. 

(Full disclosure: these are merely names the Cardinals should be keeping an eye on. It’s obviously impossible for them to sign all four of these players.)
