This is just my opinion. But in my football watching experience, I've seen two types of coaches. The one, who believes it is part of the learning process, and gives the QB the freedom to call audibles from day 1, and the other who believes the QB needs to earn the right to be able to call audibles. I don't think either is right or wrong, but I do believe if you have good people on offense, Head Coach, Offensive Coordinator, QB Coach, then you are setting your QB up for success, by not giving him the ability to audible. Less for him to think about. If you have good plays, which we do, and use a variety of formations and motion to reveal the defense, which we do, the QB has enough information to make almost any play work. I believe the success Matt has had, (& David Carr and Sage Rosenfels to that extent) is proof of that. The QB earns the right to call audibles, by first, making the most of the plays & the options those plays present him. Matt is doing excellent in that regard. Second, the QB has to have a conversation with the QBCoach/Offensive Coordinator on the sidelines, when looking at game-time photos. Talk about the last play, what you saw, what you thought, don't let them talk to you about what you should have seen, what you missed. & thirdly, the QB has to make timely use of timeouts. If you are in a position, where there is absolutely no way that you can be successful with the play you were given, call a timeout. This should happen rarely, but when it does, the QB has to recognize it. Talk it over with the coach, tell him what you see, what you think. I think this builds trust, and earns the ability to call audibles. I don't know how much of this is going on. I imagine Schaub is a sharp guy, and is doing most of it. But I rarely see Matt call timeouts. I'm watching the Seattle game, 6:31 left in the second Qtr. We are lined up in the Ace package, 2 WRs, 2 TEs, on the 50 yard line, 2nd & 6. Seattle is in nickel showing blitz, with 7 guys on the LOS. I have no idea what the play is, but there is plenty of time on the clock, we have the lead, our guys seem to be lined up correctly, and ready to snap the ball... & GK calls a timeout. It may just be me, but I think that should have been Matt who called that timeout. I believe like any head coach, GK values his timeouts, and don't want to use them unless you have to. But, he's also very conservative, and doesn't want to change the play at the LOS, unless you absolutely have to. Once Matt shows he knows when to use timeouts, he'll know when to call an audible.
