The problem with Stafford is that his OL is still bad, still without their top lineman(Warford) and they can't run the ball. They seemingly can't even pass the ball anymore.
People are becoming fed up with Stafford but it's more complicated. Plus, it's not like they have a better option currently.
In addition, this offense has been relatively garbage since the hiring of Lombardi. There was a case to be made that he should have been canned last year. I understand Caldwell wants to be loyal but that guy needs to go or Caldwell himself needs to take over the play calling. Jokes aside about his demeanor, he did well in hiring Austin and has, at least, an average defense.
