Won't slam you. He's an interesting option. But he has issues. His head ain't right like Mayfield (or our very own Tristan Hill).
"He was both a child prodigy and a child of privilege, and the combination makes him a weird fit in a football locker room. That is an environment full of people who are determined to prove a point. Rosen tends to act like he has already proven it.
"A year ago, Rosen went 10th in the draft and immediately declared, “Nine mistakes were made ahead of me. And I will make sure over the next decade or so that they will know that they made a mistake.” He later amended this to say that three mistakes were made ahead of him: The Browns drafting quarterback Baker Mayfield, the Jets drafting quarterback Sam Darnold, and the Bills drafting quarterback Josh Allen."
Jim Mora said he “needs to be challenged intellectually so he doesn’t get bored.”

Still think it's a good thought even though he will probably be looking for a starting gig.
