Let's not joke around that Romo had some really good teams around him too.
Come on.
He had some crap, but he also had some real good opportunities also.
In my opinion the Cowboys wouldn't have won the Superbowl during Romo’s time even with Tom Brady at QB.
A lot of play off games come down to a few plays regardless of what else happened.
2006 - this is the only year where it was Romo’s fault for me but that wasn't even as a QB but a place holder. Although if the kicker had put in any sort of block Romo rectifies his error by either making the first down or scoring a TD. He should have known at this point that he couldn't rely on other players to execute plays to help the team win. I don't think this team was good enough any way but I guess we will never know.
2007 - Patrick Crayton hesitating on a walk in TD to beat the eventual SB Champion. That's it. Brady couldn't catch his own pass if he made the same throw.
2009 - the offensive line got destroyed vs the Vikings. Romo had next to no chance of helping the Cowboys to winning that game.
2014 - Romo could have avoided a sack or two but he played well enough to win that game. Tight game but we didn't make enough plays at key times. E.g. Murray fumbling the ball cost 3-7 points. Bailey missed field goal cost 3 points. I love me some Dez but he knew the rules or should have done - just bring the ball down at the 1 yard line. Cost 7 points.
2016 - he wasn't given the chance to play against a secondary that should have been attacked and targeted from the very first drive. This was frustrating as I feel the defense would have played so much better for the remainder of the play offs had they won this game and they largely did a good job in the second half after a poor first half.
Other years the teams just weren't good enough.
