The member of the Cardinals who intrigues me most is Markus Golden. He had 12.5 sacks as a rush linebacker in 2016, missed almost all of 2017 with an injury, and has just recently started working back in. He isn't completely back to his old form yet, and may never be in Wilks' 4-3 defense. However, there's a chance that he could thrive if placed back into a system similar to the one he played in previously. He would be easy to fit into the current cap situation and could potentially heat up as the season progresses and he gets more comfortable. But there's an inherent risk there that he will never be the player that he was previously, so the cost to acquire would need to be low.
