 The 2010 regular season was the first year that the league used a modified version of the scheduling formula that was first introduced in , in which all teams play each other at least once every four years, and play in every other team's stadium at least once every eight years (notwithstanding the regular season games played overseas as part of the NFL International Series).Under the original 2002 formula, since the pairings were strictly based on alphabetical order, those teams scheduled to play the entire AFC West had to travel to both Oakland and San Diego in the same season, while those teams playing the entire NFC West had to make their way to both San Francisco and Seattle.In , the New England Patriots and New York Jets each had to make cross-country trips to "all four" of the aforementioned West Coast teams.
