The NFL will let us know if he's the second best QB in program history.
We'll just have to wait and see who is right.
Considering Manning went #1 overall, and Heath went #3 overall, I would say at best he is third.
In all seriousness JD is exactly what you want as a representative for your football team. Smart, athletically gifted, a pillar for the community. Add in the fact that he is black, only makes these things better for our community and nation as a whole. (by that I mean it is time finally to stop looking at a persons color, gender, or sexual orientation and pre-judging them on that criteria, and I am a die hard conservative).
Now as far as QB's, if he had went to Bama, he would have never sniffed the field, and we should name a street after him "Bounce Pass".
In the world of UT QB's, he would rank behind:
Peyton
Heath
Casey
Tony R
Condrege
and probably Bray
You are trying to span too many generations and offensive philosophies, kind of like saying D Kizer is a better QB than Montana at ND.
