The Cardinals are hoping for a major turnaround in 2020 behind quarterback Kyler Murray, but the roster still needs to be upgraded. General Manager Steve Keim has some cap space this offseason and will aim to plug holes on both sides of the ball. We will break down each position group leading up to free agency, which begins with the legal tampering period on Monday, March 16.

Free agent primer: Quarterback

Other positional primers: LB I WR I DL I CB I TE I S I RB I ST I OL

Cap hit of players under contract for 2020 (via OverTheCap.com): Kyler Murray ($7.99 million); Chris Streveler ($510,000); Drew Anderson ($510,000).

Scheduled free agent: Brett Hundley

Need: Medium

Analysis: The Cardinals have their franchise quarterback in Kyler Murray, so while several big names could be hitting the open market, the team won't be entering that fray. Instead, it will be a spectator as the likes of Tom Brady, Philip Rivers and Jameis Winston possibly switch teams.

The Cardinals do need to address the backup quarterback spot, whether that means bringing back Brett Hundley or scoping out other options. While the Cardinals hope the No. 2 signal-caller never sees the field, it's imperative to find someone who can keep the ship afloat in case of an injury to Murray. A player with mobility would be ideal so the offensive system can remain similar regardless of the quarterback.

The Cardinals only kept two quarterbacks on the active roster last season, but Chris Streveler will make his case for a third in 2020. He was signed out of the CFL this offseason and has throwing/catching/running qualities in the vein of Saints quarterback Taysom Hill. Streveler could be a gadget-play specialist if he makes the roster. Drew Anderson, who spent last offseason with the team and was added to the practice squad late in the year, will try to make an impression this summer.

While the Cardinals won't be a major player in one of the more intriguing quarterback free agency periods of all-time, the backup spot is still an important position that must be filled.

Notable past free agent quarterback signings: Hundley (2019); Sam Bradford (2018); Mike Glennon (2018); Blaine Gabbert (2017); Drew Stanton (2013); Derek Anderson (2010); Kurt Warner (2005); Shaun King (2004); Boomer Esiason (1996); Jim McMahon (1994); Steve Beuerlein (1993).
