I don't want to start the DA vs BQ debate up, but I do have a question that I hope someone can offer some intelligent insight into.  Does DA audible?  Is he capable?  Is he allowed?

I don't ever think I've seen him switch a play at the line of scrimage, and I wonder if this contributes to his inconsistency.  IMO there seems to be many situations where the called play has very little chance of success given the defense's formation yet we run it anyway.  I know there is a lot of variables that go into each play's success/failure, but I honestly don't know if we have ever changed a play at the line of scrimage in the Chud era, so I ask why?
