This is a good point. While we would all love to have a Vince Young or Johnny Manziel esque playmaker kind of talent, we really don't need it to get to the place we want to be. I kind of think of (or hope to see) Tommy as being a Zac Lee 2.0 Same mold, just a slight step up. Doesn't have a cannon, not a burner although he can definitely run, will know the offense and what the coaches are asking of him and be happy in his role. We were essentially three single plays away from being 13-1 in 2009 with a decent-turned-mediocre quarterback (due to playing injured) running the helm and taking care of the ball. If our defense can take that next step and Tommy can too, we should have bright days.
On a related note, I rewatched through the Georgia game last night and came away a lot more impressed with his performance than I originally remembered. Nothing that made you go "wow", but more than anything he had really good pocket awareness, didn't have any of those throws that went to nobody, and generally made really good decisions.
Pretty much agree with everything you said, except I hope to God he's better than Zac Lee. That offense was so inept, I got to the point where I couldn't wait until we got our defense back out there. They could atleast get us good field position for a FG, and probably had just as good or better of a chance to put 6 on the board.
