After a friend of mine did some film work and studying for his draft site, I have changed my mind:
I have Rosen, Jackson, and Mayfield pretty close. Rosen is the prototype (and deservedly) but the other two's production and the way they carried their offenses is undeniable. Probably have Mayfield 3rd based on age if nothing else; Mayfield may be the more productive passer now, but he's also two years older. How good will Rosen and Jackson be in two years?
Any of them I'd be happy with a top-5 pick on.
Darnold I have later toward the first; there are more flaws and downsides there. Still I think he's probably worth taking a chance on.
Rudolph I have as a second-rounder but not a lot of confidence in that grade until I watch more tape.
Allen is more like an end of day 2 pick for me, and that's all on upside (and I wouldn't be heartbroken in the least if I missed him in the third or even the fourth). He'll go in the first though, for the same reasons I had Christian Hackenberg UDFA and he still went in the second.

So I wouldn't touch Josh Allen with a 1-foot pole.
