Dak isn't the same without his wheels. I have no doubt he was a better player in past years than he his now. People forget that when he first started, he became known as an anti-Romo in that he didn't throw picks and make the big mistake. Fast forward to now, he's the total opposite. What's worse is that suddenly he can't play from behind, this wasn't always a problem with him.
Big game losses have gotten in his head, and i'm pretty sure tonight's game broke him mentally. Hate to say it, but I think he's done. Still a good team, but only with an outside shot of making the superbowl with him at QB. Will take a lucky run of opposing injuries and big turnovers on defense each game.
