 While teams playing against their division rivals twice each has been a tradition since at least the AFL–NFL merger, not all teams would play the same amount of divisional games between the divisions due to the imbalances that had existed.The AFC Central in between 1999 and 2001, consisting of six teams resulting in part from the Cleveland Browns relocation controversy, forced teams to play ten intradivision games in a 16-game schedule.The only time since the merger that the league has been completely "balanced" has been from 1995 to 1998 (with six divisions of five teams each) and since 2002 (with eight divisions of four teams each).
