Patrick may still achieve an undefeated season in his career, but it won't be in 2024 - much to the delight of .

On Sunday in Week 11, the suffered their first loss of the 2024 season as Josh Allen led the to a thrilling win with his late rushing touchdown. Despite entering Highmark Stadium with a perfect 9-0 record, Mahomes and his team saw their run end against the Bills, who emerged victorious with a score of 30-21.

This defeat means the Chiefs will not join the 1972 Miami Dolphins, who won the Super Bowl with a perfect record. Brady's 2007 New England Patriots came agonisingly close, finishing the regular season 16-0 and blitzing through the playoffs only to lose Super Bowl XLII to the New York Giants.

Mahomes won't accomplish an unbeaten season this year, which will allay any fears Brady may have that the two-time MVP is going to pull off the feat for another 12 months at least. Despite being a seven-time Super Bowl champion and standing as the 'GOAT', Brady has spoken in the past about how badly he wanted to pull off an invincible season.

The Patriots almost achieved perfection as they chased securing the sole 19-0 season in NFL history. Instead, the Giants bullied their way to a shocking 17-14 upset, and the 18-1 Patriots, for all the records and stats, came out of the 2007 season empty-handed.

When asked if he'd be willing to part with two of his seven championship rings for an undefeated season, Brady, 47, responded: "I would. Let's be real. Easy."

Perhaps it's not a big deal for Brady to trade his rings for sporting immortality, given his collection. However, he confessed that his defeat to the Giants remains his biggest regret during a chat with Jim Gray in 2020.

"You always think about the ones that got away," Brady said. "That was the one that got away. Michael Strahan has become a good friend. Obviously Eli [Manning] I've known for a long time. A lot of players on that team, I'm still holding a little bit of a grudge over that one because that one would have been - immortal would be the word.

"We accomplished some amazing things that year. That 2007 team was incredible. We played so well for so long. I wish that team would have been remembered amongst the all-time greats. And unfortunately, when you don't win the last game of the year, that's the reality. No one really remembers who finishes second. We, unfortunately, finished second that year."

Brady made clear that the locker room recognises the magnitude of their challenge, adding extra weight to each game's outcome. He elaborated: "The team definitely thinks about it... The closer we got to it in 2007, I wouldn't say it got more challenging, it was always very challenging. It's just there's just a lot of other teams that don't want to see you ever accomplish that. And I think that's what you always see, you see this highly competitive situation."

As speculation about an undefeated season grows louder, the Chiefs, once likened to the '72 Dolphins, are now nervously glancing at the 2024 Bills on their tail. With just one less loss and holding the head-to-head tiebreaker, Buffalo is breathing down Kansas City’s neck. As Mahomes emerges as a challenge to his ‘GOAT’ status, Brady is among those pleased with the Chiefs' stumble, not least because of his stake as a co-owner of their AFC West rivals, the Las Vegas Raiders.
