QB is a completely different gamble in itself. Regardless what many people believe, it is not an athletic position first. Please see Mr. Tom Brady, Peyton Manning etc.
QB is an intellectual position first and foremost, that take years of experience to master. You can't work out on your own throwing the balls into nets and expect an increase in performance. That is not how it works. Sitting and watching with little to no experience does not help.
Drafting any QB who barely played in HS and only 1 season in college is border line incompetent regardless of how athletic someone maybe.
