Let's get something out there: Maybe our QBs aren't good passers because our coaches are not good at coaching the passing game. I'm not talking about just throwing and catching the ball, but pass blocking (always an issue), coaching our QBs to read defenses, coaching our WRs how to get open/nuances of route running, coaching the QBs how to manipulate the defenses (how many times do our QBs look off the safety and throw the other way?), etc.
The passing game is more than just pitching and catching. There's a lot of subleties that go into the passing game that, quite frankly, you can tell GT does not coach when you look at teams that pass more. Even our QB drops are funky. We're a running team, therefore our coaches will emphasize what we do best. That's their choice. Our passing schemes from the RnS are also practice intensive. Something has to give...and it seems it's our passing.
Doesn't matter if our QB goes to elite passing camps (like Vad did) if the other 10 guys don't get the same level of coaching in the passing game.
