KC today is repeating what NE did 20 years ago. They managed to end up with the best of all worlds:
> Both teams had HCs who were objectively great at what they did/do. Reid is to offense what Belichick was to defense.
> Both HCs acquired a Super Bowl ring working under a previous (great). Reid was on Holmgren's '96 Packers staff. Belichick famously worked for the Giants between '79 and '90, most of that being under Parcells.
> Both HCs had decades of experience. Reid began in the NFL in '92 with the Packers. Belichick began with the Lions in '76.
> Both were HCs prior. Reid with the Eagles for 14 years. Belichick with the Browns for 5 years.
> A great staff recruited in part because of the HC's longevity and connections. We could go down the list.
> Both teams happened to draft some Hall-of-Fame weapons: Tyreek Hill, Travis Kelce, Gronk, etc.
> Both had strong defensive rosters. NE early on is obvious, but KC has always been good and is great this year.
> A capable veteran QB installed early on (Alex Smith, Drew Bledsoe).
> Both replaced the 1st QB with a 2nd who turned out to be the greatest QB of a generation (Mahomes, Brady) who had remarkable and unteachable instinct.
> A strong/supportive fanbase along with committed ownership (Hunt family, Kraft).
> A good (cold) homefield advantage. This probably shouldn't be ignored given how many dome teams have historically sucked (Saints, Lions, Falcons, Rams, Colts) and how many warm-weather teams just haven't been that good over the last 20-40 years: Jags, Dolphins, Texans, Panthers, Bucs, Cardinals, etc.
> A division filled with relatively inconsistent teams who can't do much to challenge and who can't sustain any momentum. The Bills, Jets and Dolphins rarely challenged the Patriots, certainly not for any sustained period. In the AFC West today, most teams are over-rated. The Raiders and Broncos aren't very good. The Chargers always seem to disappoint.
KC and NE are exceptional stories. Good for those franchises. Neither could sustain any real success before then. We should hardly be mad at those 2 organizations for randomly winning the lottery and having literally everything come together. There's no predicting who the next one will be. We may not see that level of dominance for another 15 or 20 years.
