The injury to Dak was actually a gift. He sucked the first game of the season and if he played like that in the following games, we likely would have lost as well with a mentally decapitated starting QB. In the meantime, Rush and co. found a blueprint to win by running the ball, protecting the ball, eliminating costly mistakes, and letting the defense keep you in the game, taking opportunities when they present themselves. Not forcing errant passes. Being patient and capitalize on the opponent's mistakes.
I think that is what Dak was referring to when he said, "It's so easy". At least I hope that is what he meant.
