Of course not, but you're being disingenuous. The person is pushing back against the narrative that mouth breathing Dak slobbering clowns try to push that every single loss the Cowboys ever experienced ended with a Romo interception in the end zone that swung the game from a win to a loss. If we're being analytical, I'm not sure when Romo ever "choked" except the aforementioned Giants game. He played terrible and made mistakes in a whole lot of games that they were underdogs in and weren't particularly winnable in the first place, but he never pulled a Russell Wilson and threw the ball right to another guy in the Super Bowl. People think it's a Super Bowl stopping choke-crime that Romo threw an interception in a road game as underdogs that prevented a horrible 8-8 team from getting smoked in the playoffs the next week.
Mouth breathing Dak slobbering Clowns? You think this kind of 4th grade insulting establishes you as fair minded? What it does is establishes you as being as unfairly anit-Dak as you are claiming others are unfairly anti-Romo.
Now, let's try a little reality. Romo was a very good QB, who, like Dak, had the ability to win big with the team if things went well. Unfortunately for Romo, that didn't happen, and some of it is on him, and some on the rest of the team, and some on the coaching. But if we are fair, early in his career Romo was widely criticized for making key mistakes late in games, and particularly in December when the season was winding down.
Sure, some of the criticism was probably unfair, but although I can't remember specific moments, I do recall feeling that at times. Romo improved greatly in that area as his career went on, but let's not pretend he didn't have his moments where he didn't play well or didn't make a key mistake. Hell, even Brady, Manning, Rodgers, Brees etc … had an occasional moment like that.
As for the idea that a QB or team cannot choke in a game they weren't favored to win, I disagree. If a play is available with a chance to win the game, and the QB or team doesn't make it, or worse, makes a mistake that turns the game the other way, that doesn't just get excused y saying " well, we weren't expected to win anyway". No quality athlete thinks that way, and the reality is that stepping up in those kinds of moments is how an athlete and a team go from being underdogs to being the team to beat.
