I think when the dust settles after the combine testing, interviews, etc. Darnold ends up back at the top, "down year" or not.
Maybe it's wishful thinking on my part, but he doesn't seem to have any of the character/motivation concerns that Rosen has, and he doesn't have the size/gimmicky offense/douchebag issues that Mayfield does.
Above all else though, he impresses the hell out of me with his ability to move around in the pocket and extend the play... and not in a stupid, get yourself killed kind of way. More Brady/Ben mobility than a true "scrambling" QB.
A lot of the qualities Dorsey called out in his press conference as important for a QB fit Darnold... has the accuracy, has the feet in the pocket, and actually wins.
Lastly, for as much chatter as there is about him going back to school, if say, he gets a promise that he's going #1?...there's no way he's dumb enough to go back. That, and I don't buy the shit about him not wanting to come to Cleveland... I've seen that movie before (cough, Garrett).
Anyway, just my opinion. Really pumped for the OSU game for both OSU fandom and Darnold-watch.
