New coach Steve Wilks addressed the issue on last Friday's edition of Rookie Camp Live, telling NFL Network's Omar Ruiz that Bradford is atop the depth chart but Rosen can win the job.
"We're pushing everybody to start," Wilks explained. "I've stated this several times: Sam Bradford is our starter. We gotta go out there with 11 guys and Sam's going to be the first guy out there. But everybody's fighting for a position, so I'm not going to hold (Rosen) back at all.
"I want guys competing, I want guys fighting for a starting job. Whoever ends up winning the position, that's who's going to end up playing."
Although Bradford's reputation has taken a hit via the incessant injury bug, he's been one of the most accurate -- and overlooked -- quarterbacks in the league as an intermittent starter.
It's natural for the head coach to stand behind the veteran in the draft's aftermath. We see it every offseason. Over the past 10 years, though, 20 of 27 first-round quarterbacks have started at least eight games in their rookie seasons.
After speaking with Wilks earlier in the day, NFL Network's Steve Wyche reported Monday that Rosen is already entrenched as the No. 2 quarterback -- ahead of veteran Mike Glennon.
"Over the weekend at rookie camp, Josh Rosen really impressed," Wyche told Andrew Siciliano on NFL Up to the Minute. "Wilks told me he had command of the huddle and the leadership.
Between the veteran's rest requirements and the rookie's precocious ability to process information at the line of scrimmage, there's an exceptionally fluid nature to Arizona's QB depth chart.
Bradford remains the heavy favorite to enter the season as the starter. How long he stays there is up to him -- and his increasingly fragile body.
