If it were me, I'd go back to Vick if he is 100 percent for the Cowboys, or nearly 100 percent. It isn't that you cannot lose your job because of injury because that was never true in the NFL. It is because the coach is a blank slate who is building a reputation here, both around the league and among his players, and you do not want a reputation that suggests you have your finger in the wind, and that you can be completely swayed from your plan at quarterback this quickly.
