No rookie QB is going to have any success without a running game or a solid OL. If they're having to carry the team and not being given good protection upfront it's likely to lead to a disastrous season for them and their team. Dak was a 4th round pick who didn't earn the starting job in camp, he was forced into action due to an injury to Romo. He got an opportunity and has made the most of it. He has a lot of ability and what impresses me is the way he maintains being a passer for as long as he can before pulling the ball down and running.
Unlike most young duel threat QBs who can run he's a pass first QB. He hangs in looking to throw as long as he can and that's the mark of an experienced QB, not a rookie. He plays like a veteran QB, going through his progressions and throwing to the open receivers. The poise and leadership he's shown has been remarkable. He has players stepping up around him and the chemistry this team has with him at QB has me very excited not only about this season but the future.
