I know that some want to blame the OLine for Dalton's poor play. But the Cowboys have had injuries on the OLine all season long and even with a struggling OLine many Dak critics would still say that it's all on Dak to overcome the OLine and other players mistakes or bad play no matter what.
Some thought that Dalton would be running Dak out of Dallas by playing very well and hoped that Dalton's play would be the end of Dak's career with the Cowboys. Doesn't seem like it's going to happen now. Not that Dalton was guaranteed to keep the job over Dak if he had played well, but this get rids of any "QB controversy" going ahead for the Cowboys.
