With the Arizona Cardinals opening offseason conditioning workouts Monday, the quarterback reported for duty, NFL Network Insider Ian Rapoport reported.
Not only did Rosen show up for the start of workouts, but he was also the first player in the building, per Rapoport.
Monday marks the first day Cards new coach Kliff Kingsbury will meet with his team and begin installing his new playbook. Having Rosen on hand is a positive step in the process if Arizona ultimately decides that riding with the still-growing signal-caller is the best move for the franchise.
Rosen reporting won't slow the belief that Murray remains the apple of Kingsbury's eye, but at the very least having the incumbent in the building is one less distraction for the rebuilding Cards.
