The dynasty is aging and the defense sprang leaks, and our model finally steps off the Kansas City bandwagon
Updated
For the better part of a decade, betting against Kansas City has been a good way to lose money, and the market is still pricing the Chiefs like the invincible outfit that owned the AFC. Our model sees something different this year. When we ran the simulations, Kansas City came out around eight wins, a notch and a half under a betting line that still sits above ten, and the gap is not a knock on Patrick Mahomes. It is a recognition that the roster around him has thinned, the defense lost real pieces, and the offense our grades once treated as untouchable now lands a merely good 14th in the league.
Mahomes remains Mahomes, and nothing here questions the quarterback. Our model projects a line of 3,911 yards and 21 touchdowns, right in step with his 2025 production, the work of a top three player at his position who elevates everyone around him. He is the reason the floor stays high. But there is a difference between a quarterback being great and an offense being unstoppable, and the numbers around him have quietly slid from the historic to the very good. When we ran the season, Kansas City scored 366 points, a solid total, not the avalanche of the peak years.
The skill talent is real but no longer overwhelming. Rashee Rice has grown into a genuine number one, a projected 99 catches for better than 1,100 yards, and he is the centerpiece of the passing game now. Xavier Worthy adds vertical speed at 56 grabs, and Travis Kelce, even in the twilight, remains a red zone security blanket at five scores. The addition of Kenneth Walker gives the backfield a legitimate lead runner who topped 1,300 yards. This is a good group. It is not the murderer's row that once made the Chiefs impossible to defend, and the grade reflects the difference.
The defense is where the real erosion happened, and it is the crux of the projection. Kansas City lost a chunk of its secondary this offseason, and these were not depth pieces. Trent McDuffie, one of the best cover corners in football, is gone. So is safety Bryan Cook, an 83 grade playmaker on the back end. So is corner depth in Jaylen Watson and Nohl Williams, and so is edge rusher Charles Omenihu and linebacker Leo Chenal. That is a lot of quality walking out of a unit that has to hold up against elite quarterbacks, and while the grade still lands a respectable ninth on the strength of Chris Jones and the front, the coverage took a genuine hit.
When we ran the simulations, that thinner secondary showed up in the box score. Kansas City allowed 368 points, roughly even with what it scored, and a defense that once traveled and won games on the road now profiles as merely good. Chris Jones and George Karlaftis still generate pressure, and the pass rush keeps the unit dangerous, but the days of the Chiefs locking down a game in the fourth quarter with airtight coverage look to be behind them. A pass rush can only cover for a depleted secondary so often.
The schedule compounds the concern. The AFC West is not a soft division. Denver graded out as one of the best rosters in football in our run of the season, the Chargers have Justin Herbert and a real defense, and even the Raiders added talent. Kansas City no longer gets to feast on a weak neighborhood, and six divisional games against improved competition is a heavier lift than the Chiefs have faced in years. When we ran the season, those division games were genuine coin flips rather than formalities.
So the math changes. A very good but not dominant offense, a good but no longer suffocating defense, and a division that got tougher add up to a team that wins nine or ten in a great year and eight in a normal one. That is not a fall from grace. It is a return to earth, the natural arc of a roster that has spent big to keep its stars while the supporting cast turned over. Our model sees a playoff bubble team rather than a number one seed, and the market has not caught up to the shift.
Our number sits below the line, and the bearish lean is grounded in the roster rather than a hunch. Vegas is charging a premium for the brand, for the memory of three titles and the assumption that Andy Reid and Mahomes always find a way. Our model does not price memories. It prices the players on the field, and the players on the field, particularly in the secondary, are a step down from the group that made Kansas City a machine. When the disagreement is anchored to real personnel losses, we will take the under.
The path to being wrong is short and named Mahomes. He has authored miracle seasons before, has dragged flawed rosters to Super Bowls, and betting against his ability to squeeze wins out of a thinner supporting cast has burned everyone who tried. If Rice is a true star, if the pass rush covers for the young corners, if Mahomes simply refuses to lose close games the way he has his whole career, Kansas City is right back at eleven wins and this preview looks foolish. That risk is real, and it is why the fade is a lean rather than a plunge.
But a preview has to weigh the roster as it is, and the roster as it is has holes it did not have a year ago. When we ran the season, the Chiefs were good, not great, a team fighting for a wild card rather than cruising to a bye. That is the honest projection, and it is a meaningful one, because it is the first time in years our model has looked at Kansas City and seen something short of a juggernaut.
The dynasty is not over. Mahomes is 30, in his prime, and any team he quarterbacks is dangerous in January. But the margin that made the Chiefs untouchable, the elite defense and the bottomless offense, has narrowed, and a tougher division will expose it. When we ran the simulations, Kansas City looked mortal, and our model is comfortable saying what the market is not ready to hear. This is a good team in a hard division, not the inevitable AFC champion, and we will take the under on the reputation.
Watch the secondary early. If the young corners hold up and the pass rush travels, the Chiefs will win their share and the fade will look premature. If good quarterbacks carve up the thinned out coverage, the eight win projection will look prescient. Either way, the era of pencilling Kansas City in for a first round bye is over, and our model is the first to say it out loud.
