In the Cardinals' case, Rosen gets the headlines. He was proclaimed the most NFL-ready by most draft experts of all the QBs that came out, so it stands to reason now that he is on a team people are waiting to see -- or predicting -- that Rosen indeed will supplant Bradford in the starting lineup. And it's true that Rosen has looked solid in OTAs. Those who have been out there can see it themselves, and coach Steve Wilks has definitely offered praise.
But, as noted in the headline, it's just June.
This isn't to throw cold water on Rosen expectations. Bottom line, he's the QB of the future. That's what he was selected to be, and what the Cardinals count on. There, however, is a long way between now and Sept. 9 against Washington. There is a long way between practice football without pads and QBs never getting hit (this time of year) to practice football with pads but still never getting hit (training camp) to preseason games where you can get hit but gameplans both offensively and defensively are fairly basic, to regular-season football.
