Revenge or Repeat? What the Numbers Say About Back-to-Back Championship Rematches

The 2025 NHL Stanley Cup Finals are now set, with the defending champions – the Florida Panthers – taking on the Edmonton Oilers. If you are feeling deja vu, there’s a good reason for that, because this was the same finals matchup as last year, which Florida won in seven games. 

The fact that these two teams are going against each other for a second straight season is incredibly rare, not just in the NHL, but in all of the big four sports leagues in North America.

To determine how uncommon a back-to-back championship rematch in the big four sports (NFL, NBA, MLB, and NHL) is, we went back and looked at all of the finals matchups to see how often an immediate rematch came about. We found that there were only 29 instances of this happening in modern professional sports history, including only seven times in the NHL. The rematch this year between the Panthers and the Oilers will even up the tally to 30 instances.

Repeat Showdown: Panthers and Oilers Clash Again

Since 1907, when the Chicago Cubs and the Detroit Tigers had a back-to-back championship rematch in MLB, this has happened only 29 times in the Big Four sports, with the same team winning both championships 17 times (58.6%) and a split between the two teams happening 12 times (41.4%). Based on this small sample size, the team that won the first time has a slight edge in taking the rematch, auguring well for the Panthers’ chances of beating the Oilers again.

In the NHL specifically, there have been seven back-to-back championship rematches previously, with four repeat wins (57.1%) and three splits (42.9%), so this year’s Oilers and Panthers rematch will be the eighth. The Oilers have played in a back-to-back championship once, losing to the New York Islanders in 1983 and beating them in 1984. Before this year, the most recent back-to-back championship rematch in the NHL took place in 2008-2009, when the Pittsburgh Penguins and the Detroit Red Wings split their pair of championship rematches.

In the MLB, there have been nine back-to-back championship rematches all-time. However, it hasn’t happened in nearly 50 years, as the last immediate rematch we had in the World Series took place back in 1977-1978 between the New York Yankees and Los Angeles Dodgers, who split their championship games. 

It is worth noting that the Yankees and Dodgers met in last year’s World Series and are favored by top sportsbooks to have an immediate rematch this year.

In the NFL, an immediate back-to-back rematch for the Super Bowl has only happened once. This took place in 1993-1994, when the Dallas Cowboys beat the Buffalo Bills in back-to-back seasons. The Bills lost four straight Super Bowls, though they lost to the New York Giants and Washington Redskins before they lost two straight Super Bowl championships to Dallas.

In the NBA, an immediate back-to-back championship rematch in the NBA Finals has happened 12 times, so it’s happened more often than in any of the other pro sports leagues. The first time this happened was in 1952-1953, when the Minneapolis Lakers beat the New York Knicks two years in a row. It most recently happened in 2015-2018, when the Golden State Warriors and Cleveland Cavaliers met four years in a row. The Warriors won three of those seasons, including back-to-back championships in 2017 and 2018, during the height of their dynasty.

Soon, we will find out if the Panthers will join the list of repeat champions or if the Oilers will earn themselves a split. For more information about how we conducted our analysis, see the tables below.

Methodology:

We analyzed all instances in the MLB, NBA, NFL, and NHL where the same two teams met in the finals in consecutive seasons. Each two-year window was treated as a single rematch event, regardless of other meetings. The only exception was Warriors vs. Cavaliers (2015–2018), which was counted as three distinct rematches using this format.

Each matchup was labeled as a Repeat Win (same team won both years) or a Split (each team won once). Data was verified using ESPN and official league sources.
