Despite signing Sam Bradford to a $20 million contract, the Cardinals moved up in the 2018 NFL Draft to snag Josh Rosen with the 10th overall pick. 

It was reiterated time and time again that Bradford would be the starter, but just a matter of weeks into offseason activities it seems like that narrative is open to changing. 

Rosen was deemed but many as the most pro ready signal caller in the draft, and he's proving that early on in practice. 

The intention may still be to start the injury-prone Bradford, but by all accounts Rosen is developing quickly and could be hot on his heels by the time the preseason starts. 

So much so that even Cardinals head coach Steve Wilks admitted that Rosen could be the starter come week one. 

When asked if it was out of the realms of possibility that Rosen could usurp Bradford as the number one QB on the depth chart by the start of the regular season, Wilks replied: “No, it’s not.”.

“I talked about it from day one – the best 11 are going to play,” Wilks added per the team's official website. “Sam (Bradford) is the starter, and when he’s healthy, he’s great. But everybody is competing to be out there on the field. Competition is a great thing. It makes us all better.”

Clearly Rosen has impressed the first year head coach, and he went elaborated a bit regarding what has changed since seeing the former UCLA in action on the practice field. 

Wilks lauded Rosen's intelligence and ability to learn on the fly, but remained cautious, reminding everyone that the first round pick is still a rookie and he's certainly going through some growing pains. 

"This guy is extremely smart," he said of Rosen. "I mean, his ability to see certain things from the defense, and pick it up quickly, and execute ... I don't want to say this, but he has the mindset of a vet. The way he sees the game.

"He's not playing like a vet. Make sure you guys understand that. He's still a rookie, OK? But he sees things, like I said before, through a different lens. And he picks it up quickly."

Wilks is leaving all eventualities open as the offseason progresses, and whilst the idea of Rosen blowing the coaches away with his play and smarts is exciting, he's in a race against time to overthrow the veteran Bradford before week one. 

In all truth, it's probably not in his best interest to be out there starting the season, and his development will be hugely aided by sitting and learning behind Bradford for a few weeks at least. 

However, as Wilks alluded to, Bradford's health is a huge quandary and thus, having Rosen be so impressive in camp could be a huge boost to the Cardinals should the incumbent atop the depth chart go down at any point this season.
