If you’re a stickler for milestone purity, if you don’t believe it’s fair to assess the Cowboys or any other NFL team until a quarter of the season is in the books, you must wait to read this until the first quarter of Sunday’s game against the New York Jets is over. Dallas had just completed its third consecutive 12-5 regular season heading into that playoff game against the Packers. The Cowboys aren’t a bad team; the offense should win more games than the defense loses, which is at least somewhat by design.
