Early on in the process, I didn't know what to think about Darnold. Rosen is more polished as a passer, and so I gravitated toward him. The more you watch Darnold, though, the more you get it. He reminds me of Roethlisberger. Great pocket presence, ability to make steps here and there to avoid the rush. Definitely got moxie. I think he'll pan out.
Right now I have 4 tiers:
Darnold/Rosen
Mayfield
Allen/Jackson (way down yonder on the Chattahoochee)
Everyone else
