Some were wondering how often an NFL team has beaten another team three times in one season. Well, I've found the stat.
Since the NFL-AFL merger in 1970, teams have played three games in the same season 53 times, but only 17 of those included teams that won both regular-season matchups, according to STATS Inc. In 11 of those 17 games, the team that won the first two games also won the third, the last time by St. Louis over Seattle in 2004
Dallas’ loss to the Cardinals was in the 1998 playoffs after the Cowboys won the two regular-season meetings. That postseason defeat was at Texas Stadium.
Is defeating a team three times in one season difficult? You bet. Is it impossible? Nope!
