Yeah, I live in Charlotte and follow the Panthers pretty closely.
Admittedly Corral hasn't had a huge body of work (and he got injured his rookie year), but I have seen all of his action in preseason games. He has honestly looked completely lost every time he's on the field. The book on him coming out was great arm and athleticism, but also lacking in many of other attributes necessary to be a functional qb. So far that has proven to be highly accurate. He played in a very simplistic offense in college and has struggled mightily adapting. Corral panics and gets happy feet in the face of pressure or when he doesn't understand what the defense is showing. He'll give up on plays prematurely and deliver inaccurate passes because of poor mechanics. From my viewpoint he is just overwhelmed and lacks confidence.
I guess some team will take a chance on him because there's no harm in trying, but I don't see him turning into a successful reclamation project.
