There's only two players I would trade up for: Josh Rosen or Josh Allen. Rosen is light-years ahead of every QB in this year's class. Josh Allen has really big potential, he could be a playmaker for a long time. Lamar Jackson I would draft if we stayed put, I would not trade up for him because his a boom or bust prospect. He is the fastest man on the field and has immense physical talent, solid arm but he sees ghosts and often only goes through one read. He is a faster version of Michael Vick.
*Sam Darnold needs to stay in school. He is just not ready yet, he makes a lot of throws that would be picked off in the NFL and if he goes to a team with an unstable OL, keep in mind he is very slow and not very mobile. Shows flashes of being an elite QB, I just don't think he's ready.
*Baker Mayfield I would not take, period. Too small, not very fast, shotgun only passer and not a pocket passer. His arm is ok though.
