This is true. Bit a couple of things, for one, Consentino never even played QB in HS. So..... But again, I am talking what QB's even played at a P5 level, let alone played well and were either good college players (like Pryor) or NFL prospects. I think Jurkovec is going to be one, and honestly if it wasn't for Pickett, he would have transferred from ND to Pitt.
Your point though is valid and it is their fault. But look at the great Tyler Palko and Anthony Morelli. Really, Palko was a good college QB, Morelli less so. In High School, we thought these guys were for sure NFL guys.
And I will give you this list.
Dan Marino. Jim Kelly. Joe Montana. Terry Hanratty. Tom Clements. Joe Namath. Johnny U. Only one went to Pitt, so this isn't a new development.
