On top of that, we have no idea when a play is audibled out of. It is really easy for me to say it is a bad call if it doesn't work. But it was called for a reason. Does the team know something about a formation that tips them to try something? I submit that they usually do. For instance Carr's INT of Big Ben. He knew Haley likes to make that throw against Safety over the top. Carr picking it off doesn't mean Haley made a bad play call. It means Carr read it, and gambled. If he misses that pass Pittsburgh scores possibly because no one was behind the WR when Carr laid out.
