Word from Arizona at the end of the team’s offseason program was that rookie Josh Rosen has done well, but that Sam Bradford remains the likely choiceto start at quarterback for the Cardinals come September.
Trying to keep that spot on the depth chart hasn’t gotten in the way of Bradford aiding Rosen’s transition to the professional level, however. Bradford told Rosen after the draft that he would be an “open book” for the first-round pick and Rosen said Bradford’s been true to his word.
Rosen said during minicamp that Bradford has been “helping me out a ton” and that he’ll return the favor any way he can during his rookie season.
