I'm not denying that Dak should have played better. And was a big factor in why that game turned out the way that it did. I'm just not for completely absolving the defense of their poor performance by putting it all on Dak. Nor do I want our defensive players to have the mentality that it's okay for them to play badly if the QB has a subpar performance or just not take responsibility for how they perform in a playoff game, by deciding that they are going to give up or not even try if the QB isn't coming out lighting up the scoreboard or throws picks.
While Dak's QB play is compared to other QBs who performed better in the playoffs. The defenses effort can also be compared to how other defenses played in the playoffs. We saw offenses go through 2 or 3 quarters without putting up a lot of points and defense that didn't use that as an excuse to give up TD drive after TD drive. And saw QBs who turned the ball over and yet their defense still did enough to keep them in the game. So our offense stalling out for a few quarters, isn't an excuse for the defense to perform badly all game long, to the point of leaving some of the GB WRs so open, that there wasn't even a Cowboys defender in the screen shot of some of the frames. Dak isn't to blame for that.
And even in the instance of the Cowboys moving on from Dak, I don't want the next Cowboys QB to be saddled with a defense who is going to decide that they'll give up during the game in the offense isn't playing well. Or that they are going to blame the QB for their poor perform, if he doesn't happen to have a good game himself.
