Darnold - is your blue collar over achiever in college but he will be Andy Dalton II
Allen - is a more athletic Paxton Lynch and will struggle with accuracy and the speed of the game not to mention reading defenses. He is probably the most raw out of all the QBs.
Rosen - is too Cutlarian/Rob Johnson for me and has very little fire in the belly to win. His numbers never improved throughout his college career but oh he has such a natural easy throwing motion.
Mayfield - could be the next Russell Wilson but I just don't think a team is going to spend a top 4 pick overall on a 6' QB. It has never happened. On top of running a high school spread offense where all the WRs are wide open and the fact he is self-promoting attention whore doesn't help him either. But it does seem he has a fire in the belly but do GMs trust that in the first 5 picks?
Jackson - a taller thinner Vick that has accuracy issues as well.
My prediction order for the QBs in this year's draft.
Darnold will go first.
Allen will go second.
Rosen and Mayfield fall to some degree with Mayfield possibly falling to the 2nd just like Brees did because of height issues.
Rosen will go mid-first to late first because of his "pretentiousness and concussion issues" and fire in the belly issues IMHO.
Jackson will go in the 2nd and would probably go in the first IF he were open to being a WR.
