I think the big 3 are clearly: Burrow, Eason, and Fromm, probably in that order. I think Eason has the best arm and Fromm has the best mechanics and smarts. I get that Burrow is the most productive, which means something, but he's really 3rd on my board if I'm evaluating long-term potential.
Herbert doesn't compare to these guys in terms of performance, particularly in big games. He's too much of a spread QB and not enough of a real passer.
Hurts, Newman, Mond, Montez, Love, Tate, Patterson: passers that use their arms instead of their hips to throw, their legs instead of their minds to find open passing lanes. They are each too much of a project to become a good pocket passer, and I don't want to convert to an offense where pocket passing isn't a centerpiece of it. (I like spread formations and the occasional spread rushing or screen concept, but I don't like dumbing down the passing game).
My top sleepers are Mason Fine, James Morgan, and KJ Costello.
Fine: Maybe he's not quite Russell Wilson, but they do have pretty similar games. He's a good passer and scrambler.
James Morgan: Nice arm, good size, good mechanics. Smaller school and just above average performance, so there are certainly questions to be answered there.
Costello: Worth a look, but you have to really wonder about injuries.
