Bree's was 6 ft. Young is 5'10'' - Brees had around 5 lbs on him (which isn't a lot till you realize at that size it actually is).
I don't even think he's a Brees type.
The consensus round 1 types seem to be Maye and Williams (1 and 2, either/or), Daniels has clearly made his way into round 1 with his play this year but where, so much variance with the guy can see him going anywhere from 3-20.
Sure, there are years that guys get pushed into the 1st but there are just as many years as guys falling out (Levis). From what I've read, there doesn't seem to be any other QB that could make the 1st round. Penix, McCarthy, and Nix have significant warts to them and just don't see them as worthy 1st round picks.
But Justin Fields will end up netting a 1st and more.
