It’s likely the Arizona Cardinals have a plan to attack free agency and the NFL Draft. They are going to need to upgrade or add depth at a number of positions.
They will add from both, just like most teams. However for the Cardinals it’s a fine line which positions to target in free agency and then which ones in the draft.
For example, the Cardinals may be better suited to draft an offensive lineman rather than find a grizzly old veteran. The Cardinals have been sort of a hit and miss team with free agent offensive linemen.
