It's the revisionists history, just like in the other thread about how defenses make Dak beat them. As some act like this is a thing defenses do specifically for Dak. When all defenses design their game plane around making one of their top priorities stopping and limiting the QB. They just all do it in different ways. There are certain defensive game plans in which Dak didn't and couldn't over come. Just like there were certain defensive game plans in which Romo didn't and couldn't overcome,
All results leading to the same which is this franchise having failed to take the next step with both Dak and Romo, no matter how well they have played in the regular season or how promising their teams looked going into the playoffs, that they could either get to the Super Bowl or at least to the NFC Championship game. There is no denying that Dak could and should have played better against the Niners. But there is a lot of revisionists history in acting like defenses didn't have the correct game plans to shut down or limit Romo's offenses. Philly had the Cowboys offense to 6 points, the Vikings held the Cowboys offense to 3 and there were other teams that managed to come up with good enough game plans against Romo lead offenses, that he only has 2 playoff wins in his career.
Even if Romo's teams were as bad as some insist, it still means that Romo in the end couldn't do enough to overcome and beat enough teams to get the Cowboys to a Super Bowl.
