Meltdowns are as much a part of the NFL sidelines as cheerleaders and first-down markers. It seems every week a receiver retreats to the bench yelling at his quarterback, who usually barks right back.
Last weekend it was Andre Johnson and Matt Schaub screaming at each other.
Sometimes it's players directing their anger at their coaches or even coaches throw barbs — or in Buddy Ryan's case, a right jab — at a fellow coach.
Even superstars aren't immune from the emotions of the game.
Peyton Manning and Tom Brady, who meet up for the 14th time Sunday, have had their famous fits, Manning with center Jeff Saturday and Brady with offensive coordinator Bill O'Brien.
Here are six of the most celebrated sideline scuffles in NFL history:
MAD MANNING: During the Colts' run to Super Bowl in 2005, a request to "run the damn ball" by center Jeff Saturday after three straight incomplete passes by Manning against the Rams pushed the perfectionist passer over the edge. Manning jumped off the bench and began screaming at his center, "Hey, quit calling the (expletive) plays, all right?" They later hugged it out, and like most fights, they also kept the fallout in-house. Only, Manning was miked up for this particular game, informing Dallas Clark and Brandon Stokley moments after his blowup that his heated exchange would make for good TV, and sure enough, it became an instant, infamous classic.
INCENSED BRADY: Three Super Bowl rings didn't make Brady immune from questioning by his offensive coordinator in a game against Washington in 2011. Brady got into an obscenity-laced shouting match with Bill O'Brien, who sought an explanation but instead got an earful after Brady threw an interception in the red zone. Backup quarterback Brian Hoyer stepped between them and coach Bill Belichick finally intervened. Afterward, Brady said he deserved the tongue-lashing from O'Brien, suggesting when "you make a bad throw, you're supposed to get yelled at by your coaches." By that standard, Tim Tebow's ears might still be ringing even though he hasn't thrown a pass this season.
COACHES CLASH: The most famous fight at the Houston Astrodome wasn't Muhammad Ali's bout against Cleveland Williams in November 1966 but Ryan's bout with Kevin Gilbride on Jan. 2, 1994. It was late in the first half of Houston's 24-0 victory over the New York Jets when Ryan, the Oilers' defensive coordinator, took a swing at Gilbride, the Oilers' offensive coordinator. Ryan was 59 at the time, Gilbride was 42. Ryan threw a right-handed punch at his head. Players had to jump in and pull the two apart. Two days later, Ryan said that Gilbride would be "selling insurance in two years."
