The Dallas Cowboys have not been a serious team for most of the season, but they are absolutely for real after they took down the Kansas City Chiefs on Thanksgiving.
Losing ground in the AFC West, the Chiefs had their backs against the wall, so Dallas got their best effort. Patrick Mahomes made some otherworldly plays to stay within striking distance, but Dak Prescott was better. The Cowboys' defense was better, and Brian Schottenheimer called a better game than Andy Reid.
It seems that the league-wide perception about Dallas has changed. Old friend Stephon Gilmore led that charge after the win by making a loud statement about his former team.
