That's somewhat true - we've drafted some players like that, although, it's also somewhat overstated. Also worth pointing out - none of them were QBs who can be the face of your franchise going forward.
So you would down grade the OLB, and LG position because you didn't want to pay proven players on your team?
So after you let them walk then what? Except a drop off in performance or wish that a rookie could play at ALL Pro levels as BIG Q, and Darius Leonard.
