When Tyler Bray was here, he played all the way through his college career and went into the league. So did Dobbs. They started at UT and then were on NFL squads long enough to make money that anyone would call a financial success. Since those guys, we have not had a starting QB play out his whole career at UT. (Arguably, Worley did, but he got injured and didn't finish his senior season.) The QBs who transferred out from UT usually did not have success:
Nathan Peterman -- the EXCEPTION: he was good at Pitt, drafted by Bills, and is still getting paid to play football
Quinten Dormady -- played for Houston and Central Michigan, no pro career
Jarrett Gurarantano -- terrible at Wazzu, will not even be sniffed by the NFL
J.T. Shrout -- was playing well at Colorado, long-term effects of his injury remain to be seen
Brian Maurer -- nobody wants him or he chose to get out of CFB
Harrison Bailey -- TBD
What's my point? What's my "agenda"? None. I'm just stating these facts to see if anybody on VN wants to comment on it.
EDIT: Diderot's Ghost reminded me about Riley Ferguson. He was successful at Memphis. Did not have a pro football career.
