What is the NFL's Equivalent Rivalry?

With football the injury rate is high and the careers are shorter and the salary cap is the great equalizer among NFL teams. Most NFL teams could care less about rivalries and spend all their efforts trying to get to the playoffs and the championship.

The way the league sets up the game schedules, you may only have the Jets and Giants play once every four years. So many geographical rivalries just don't happen. Even division rivalries are only two games per year so who can get very excited about a 1-1 split.

Baseball is the most apt to develop rivalries because the season is so long; you might have 'good games' in a rivalry against your nemesis, and consider it a statement if you sweep a series in April. It doesn't need to have much bearing on the playoff picture as the season still has a long ways to go.
