All the QBs on that list are not mobile Qbs who relied on their ability to scramble around to make plays. Also this RG3 second ACL injury on that knee. I think he will be fine to come back, but if he tears his ACL again his career is over.
Except they hired the great Dough Pederson instead. Whom was coaching HS football like 4 years ago. He was the Eagles Qb coach last year and Vick was awful. I don't see how this is a good move.
