As we continue to get hyped up for the NFL Draft in April, one thing we have to keep in mind is that free agency comes first. The market opens for players to move around on March 12th and it will undoubtedly change how teams approach the draft. One of the positions that the Cardinals desperately need to address outside of the quarterback and their offensive line is outside linebacker. Sam Acho and O'Brien Schofield have not proven to be consistent pass rushers that can get to the opposing quarterback. That is why Steve Keim, Bruce Arians and co. may look at bringing someone else in. According to Mike Jurecki of XTRA 910, that someone could be former Chargers linebacker, Shaun Phillips. It is important to keep in mind that the tweet says Phillips has interest in the Cardinals, but makes no indication that the Cards have interest in him. Still, they may consider bringing him in for a look given his track record over the years.
