The defending-champion Chiefs head into their opener Thursday night at home against Detroit having won eight straight regular-season openers, which is tied for the fifth longest streak of the Super Bowl era.
Kansas City last lost in Week 1 back in 2014 with Alex Smith at quarterback when they fell 26-10 to Tennessee in a game played before Mahomes had even made his college debut at Texas Tech.
They won the next three openers with Smith at QB and then all five since Mahomes became the starter, scoring at least 33 points in the last seven Week 1 games.
They have a long way to go to catch the longest streak ever as the Cowboys won 17 straight openers between 1965-81. The last team to win more than eight straight was the New England Patriots, who won 10 in a row from 2004-13.
Mahomes has been particularly sharp to start the season, throwing at least three TD passes in all five season-opening starts in his career for the longest streak ever. The only QBs to have more than five career Week 1 games with at least three TD passes are Tom Brady (nine), Dan Marino (seven) and Drew Brees (six).
In fact, only nine teams other than the Chiefs have had five Week 1 games with at least three TD passes in the last 20 seasons. The Bengals have the longest drought of that kind with none since Boomer Esiason did it in 1988.
