NFL fans were treated to a back-and-forth playoff showdown between the Bills and Chiefs that felt endle s.Just as quickly as the Chiefs scored, the Bills answered, the teams trading leads until the two were knotted 36-36 and headed for overtime Sunday night. But that was where the see-saw action ended. Patrick Mahomes drove Kansas City 75 yards in just eight plays to end the game 42-36and send Kansas City to the AFC championship Sonny Gray Jersey game.DeCOURCY: Per NFL overtime rules, if the team with po se sion to start overtime scores a touchdown on its first drive, the game is over. Theother team does not get a chance to answer. The Chiefs won the to s and immediately scored, preventing Josh Allen and the Bills from having a chance to respond.MORE: "The rules are what they are and I cant complain," Allen said after the game. "If it was the other way around we'd be celebrating. We Adam Ottavino Jersey didnt make enough plays tonight."NFL overtime rules have been sudden death since 1974, when the league first adopted the policy. It wasn't until 2010that the rule was changed to give teams a chance to respond to an opening-drive field goal in the playoffs, and in 2012 for regular-season games.MORE:This is far from the first disappointing postseason overtime ending for a team. In Super Bowl 51, the Patriots scored a touchdown on the first drive of overtime to walk off the Falcons and win the title without Atlanta getting the ball. In the AFC championship game two years later, the Patriots again benefited from the rule as they won the to s against the Chiefs in a 31-31 game and immediately scored a touchdown to walk off Mahomes and Co.IYER:Many NFL people saw the Bills' defeat as more a product of their defense than the overtime rules. After all, Buffalo scored the go-ahead touchdown with 13 seconds left in regulation and still allowed Kansas City to move 44 yards to get into field goal range and send the game to overtime. eventually tie the game. That defense then put up little fight in allowing the Chiefs to march down the field in overtime to score a touchdown with ease.Play better defense. Dont cry about the rules. Louis C.C. Sabathia Jersey Riddick (@LRiddickESPN) Sort of felt like allowing the Chiefs to go 44 yards in 13 seconds to tie the game helped decide the playoff gmAlso the Chiefs defense continually blowing coveragesJosh Allen and Mahomes being incredibleSome questionable play calling on both sides.But sure, it was a coin Geoff Schwartz (@geoffschwartz) Coin flips dont rush/cover/tackle Damien Woody (@damienwoody) If you have problems with the overtime rule then youre ignoring the fact Kansas City went from their 25 to Aroldis Chapman Jersey the other 30 in 13 seconds. The Bills defense had more than a chance. Football is three phases - Buffalo learned about defense, Green Bay learned about special teams. Chris Kluwe, Irredeemable Pudgy Nobody (@ChrisWarcraft) I dont wanna hear overtime rules! Stop em or give up 3 both teams still playing Marcus Spears (@mspears96) MORE: Others were disappointed that a game that provided as many thrills ended with Allen losing because he called tails instead of heads.This game was ruined by a coin flip. Please change this .-Sincerely, Everyone. Kurt Benkert (@KurtBenkert) So whoever win the coin to s win the game? Saquon Barkley (@saquon) Great game by both teams but the overtime rules have got to change!! No coin flip should have that much power Amon-Ra (@amonra_stbrown) As much as I love the NFL I hate the overtime rules. Feels so unfair Buffalo doesnt get a chance to answer that. Matthew Berry (@MatthewBerryTMR) The NFL Adam Lind Jersey is the greatest league in sports because of the parity. The last team drafts first, the first team drafts last. Not allowing Josh Allen, the best player in todays game, to touch the ball in overtime is one thing the must fix.
