This is like the worst subjective fan coping trope ever created.
Let's get real. Most outcomes in sports are determined by the team that makes the fewer mistakes. If an offense scores a TD in football, someone on the defense missed or was unable to finish an assignment. If a goal is scored in hockey, there was a defensive breakdown on the other team. In baseball, a homerun is 99 times out of 100 a mistake by the catcher/pitcher.
Saying the "Mets lost it more than the Royals won it" is laughable. Yes, the Royals took advantage of the fact that the Mets made more mistakes, but that's what good teams do. Not only do they by and large make a lot less mistakes, they take advantage when another team screws up. The Mets are an average defensive team, and the right side of their infield is especially suspect. That got exposed badly over the last 3 games. As did the Mets bullpen.
The Mets didnt lose out of some sense of charity, they lost because the Royals were a far better team who got a lot of timely hits and who took advantage of the Mets mistakes.
