Why would anybody want Josh Rosen, that's the question to ask. Cards had to cut losses and go with Murray. Rosen's value is low because he played poorly last season, and he regressed, wasn't accurate or decisive. Fair market value is what others perceive, and Rosen is not coveted by other teams. He is Jay Cutler 2.0 at best, and a 3 year flame out at worst, there is a reason he was the 4th QB chosen last year.
