Sure, there are the hard hits and the acrobatic catches, but for all the on-field fireworks, the NFL is a league that is largely defined by its team and player rivalries.
Take the New England Patriots vs. the New York Jets. While the Patriots have dominated this matchup in the last few seasons, the Jets (and their fans) take pride in spoiling the record of their rivals in Massachusetts. Back in 2009, then-new Jets coach Rex Ryan was making headlines for his brash behavior and predictions in the press. Players on the Jets called it their version of the Super Bowl. Gang Green ended up winning, their first home victory against the Patriots at home since 2000. Of course, no play in the history of this rivalry will ever quite top the Butt Fumble. Quarterback Mark Sanchez took off on an ill-fated run that ended in a collision with his tackle's rear end, a fumble, and one of the most infamous plays in a generation.
Another heated rivalry is the Cowboys and the Redskins. These teams often compete for the division title, and unlike other matchups, the balance of power in this one can change from year to year. In 2016, two hot tempers collided when Washington's Josh Norman had to cover star Cowboys receiver Dez Bryant. The two exchanged shoves and taunts all game; afterward, Dez called Norman "extremely soft" in an interview.
