There are a few aspects of Josh Rosen that I really like. He is accurate, and that's the most important thing. He is smart, and that's crucial for the offense we're running now. He has arm talent, with a solid delivery, power, and release quickness to make the throws. The talent is definitely there to be a successful pocket passer.
His line was awful. His decision making was poor. His processing time was slow. Those are all things typical of rookies on bad teams. Generally, they're all improvable. Physically he's a solid pocket passer with decent size and arm strength, but he's not a mobile QB--and I'm completely comfortable with that because I'm not a fan of putting a good QB at risk by running him.
Assuming he can become the locker room leader we are hoping he can become, on the field will be about how hard he works and how much he improves on the mental side, because this offense requires a lot mentally. Rosen has the capacity to excel there …. but last year he definitely looked like a rookie. Having more INT's than TD's is never acceptable, you want that to be 2 TD's or more for every INT. But, this will be his 4th OC in a year, so he hasn't had the best situation.
He'll get his chance sometime in 2019. When he does … he needs to be better prepared and process quicker. He needs to avoid the INT's. He needs to improve. But our OL will be better than Arizona's was. Our offense as a whole will be better. He is unlikely to face high expectations. The stage is set for him to improve.
