This marked the first time the NFL has scheduled a Sunday night game opposite a World Series contest that is not a seventh game. The league explained that the decision of which game to show in this time slot was made with an eye toward minimizing the possibility that one of the competitors would be from the same market as a team participating in the World Series – New Orleans has no Major League Baseball team and the Pittsburgh Pirates were considered long shots to participate in the post-season (and indeed, they posted the worst record in Major League Baseball in 2010). There was also a feeling among the schedulers that the Steelers have a following independent of other sports.
