Super Bowl three-peat would make Chiefs greatest dynasty ever 

The Kansas City Chiefs are headed back to another Super Bowl after defeating the Buffalo Bills 32-29 to win another AFC title on Sunday. While any Super Bowl trip is a big deal, this one creates the possibility for the Chiefs to accomplish something that's never been done. 

And if the Chiefs pull off the unthinkable and complete the three-peat, winning their third straight Super Bowl, they will plant their flag as the greatest dynasty sports has ever seen. That's a big statement history buffs may scoff at, but it simply speaks to reality of the situation. 

The last time any major professional franchise won three consecutive championships was in the NBA with the Lakers. But when Shaquille O'Neal and Kobe Bryant led Los Angeles to three titles in four NBA Finals appearances in a row, they were doing so with a more star studded roster and steamrolling over teams. 

Shaq's dominance at that time was almost unfair and would've probably led to even more success if they stayed together. 

Around the same time, the New York Yankees won four out of five World Series, including three straight from 1998-2000. They actually reached the Fall Classic six times from 1996-2003. 

However, the Yankees were taking advantage of an unbalanced MLB system, spending significantly more money on their roster than most other teams. The talent level on the Yankees and the disparity of their payroll compared to smaller markets will forever be part of their dynasty. 

The Dallas Cowboys lifted the Lombardi Trophy three times in the 1990s, but they failed to reach three straight Super Bowls. The Edmonton Oilers won four Stanley Cups in the 1980s and then even one more a couple years after trading Wayne Gretzky, but those teams were loaded and still didn't do it three years in a row.  

Staying in the NHL, the New York Islanders won four straight Stanley Cups from 1979-83 and the Montreal Canadiens are owners of multiple three-peats. But those championships came in an era with far fewer teams than what the Chiefs deal with in the NFL and they also didn't have to worry about free agency or a draft format that rewards the worst teams with high picks to generate parity. 

Despite the league wanting parity, the Chiefs have continued to reign supreme. 

Bill Russell led the Boston Celtics to 11 NBA titles, but the NBA had eight teams at the start of his run and only 14 at the end. That's compared to 30 currently in the NBA today. 

No dynasty of the distant past had to overcome as much as Kansas City has to in this era. 

The Green Bay Packers were champions three years in a row from 1965-67, but only two of those were won in Super Bowls.  

Of course, the only true argument against the Andy Reid, Patrick Mahomes and the Chiefs as the greatest dynasty is what Bill Belichick and Tom Brady achieved over two decades in New England. But taking nothing away from six rings and nine Super Bowls, they were never able to three-peat. 

The Patriots did make it to three straight Super Bowls from 2016-2018, losing in the middle year to the Eagles, the same franchise now standing in the way of the Chiefs and history.
