My honest guess is because Dan Snyder probably told Gruden that if he wanted to be guaranteed one more year as HC, then he had best play RG3 no matter what.

Sure Gruden can play whoever he wants in "theory" but all that would end up bringing him is a public / national firing.

With RG3 this is probably a 3 or 4 win team. With some other QB and the same ownership / management - we are probably a 5 or 6 win team. Nothing is going to change any time soon until Snyder and company are gone.
