Isn’t the NFL just full of surprises? Just when you thought these last two undefeated heartthrobs of 2025, the Philadelphia Eagles and the Buffalo Bills, would keep strutting their perfect records down the field, they both decided to drop the ball this weekend. Looks like the league just got a little messier and a whole lot more unpredictable.

After a season of jaw-dropping plays, last-minute heroics, and fans biting their nails, the NFL’s last two undefeated teams finally bit the dust this past weekend. Say goodbye to perfect records, and hello to the chaos of parity, heartbreak, and some seriously spicy football drama.

Eagles’ Fourth-Quarter Fizzle: From Swagger to Stumble

If you had tickets or were streaming from Lincoln Financial Field last Sunday, you witnessed the Eagles looking like they had the game in the bag, until they didn’t. The Philadelphia Eagles, fresh off a 4-0 streak, seemed poised to keep the undefeated train chugging along as they led the Denver Broncos 17-3 entering the fourth quarter. But football, ever the unpredictable beast, had other plans.

Cue the Broncos’ jaw-dropping comeback. Denver, fueled by Bo Nix’s razor-sharp touchdown pass and J.K. Dobbins’ powerful rush, flipped the script and marched to an 18-point fourth-quarter spree, ultimately snatching a 21-17 win out of thin air. That kind of turnaround? It’s the kind of heartbreaker that leaves Eagles fans clutching their green jerseys, and biting their nails.

The Eagles offense, normally a sleek machine, hit the brakes hard. Jalen Hurts, Philly’s star QB, was sacked six times, and saw his normally dynamic offense stifled, while running back Saquon Barkley barely got a chance to shine with just six carries on the day. Penalties, four in the final quarter alone, didn’t help their cause either.

For a team that had been the NFL’s shining beacon of consistency, this stumble raises questions. Could fatigue be creeping in? Was the weight of maintaining perfection finally too much? Whatever the cause, it was a reminder that in the NFL, no lead is safe, no matter how big.

For the full breakdown, Fox Sports offers a thorough recap of the NFL’s undefeated teams and their surprising fates this season.

Bills’ Slip in the Snow: A Chilly Loss at Home

Meanwhile, up in Buffalo, the Bills were hoping to keep their spotless record alive on their home turf. The Bills (also 4-0) welcomed the New England Patriots in what should have been a battle of titans, but it ended with a slightly sour taste for Buffalo fans.

The Patriots, led by rookie kicker Andres Borregales, stole the show with a dramatic 52-yard field goal in the final 15 seconds, sealing a 23-20 win, and ending Buffalo’s undefeated run. The Bills fought hard, with Josh Allen throwing for 253 yards and two touchdowns. But, alas, the day wasn’t without its costly mistakes—Allen threw an interception and lost a fumble, and the Bills committed a staggering 11 penalties totaling 90 yards.

Buffalo’s usually sharp offense felt the pressure, and New England’s Drake Maye had a solid game, completing 22 of 30 passes and playing turnover-free football, a key factor in the Patriots’ victory.

The Eagles and Bills Have to Lick Their Wounds

Both teams will be licking their wounds this week, but will be back with fire in their eyes. The Eagles look to bounce back and shake off that late-game stumble. With talents like Hurts and Barkley, they have the tools, but they’ll need to tighten up protections and cut down on those costly penalties.

Meanwhile, the Bills will be eager to return home and refocus. Josh Allen’s flashes of brilliance remind everyone why this team is still a powerhouse, but the penalties and turnovers must be addressed if they want to stay in the hunt for a deep playoff run.

For the football fan who loves a little drama, the end of undefeated streaks is just like a juicy plot twist in a yummy, binge-worthy series. It means the unexpected can, and will, happen, and every game counts that much more.

The NFL season is wide open now, and that’s exactly what keeps the game so irresistible: you never know when a team will fall, a player will shine, or a moment will become legendary.

So buckle up, football fans. The ride is just getting started.
