Somebody correct me if I'm wrong.
Doesn't Aaron have the option to audible out of most plays?
From what I have heard from ex qb's, the game plan is put together, the QB is included, suggesting some plays or objecting to some.
That doesn't mean the plays are put in it taken out, it means he has input.
There are always options to every play.
That is where Aaron comes in reading the defense and deciding at the line what to run.
Veteran qb's basically call the game, staying within the gameplan.
EDIT
Gregg Jennings has become a Cowheard puppet.
No credibility anymore.
