The NHL introduced overtime in 1921. It originally began as an additional 20-minute sudden-death period of five-on-five action before being trimmed to 10 minutes in 1927 and five minutes in 1983.
However, the league allowed games to end in a tie until 2005, when the NHL introduced the shootout in the regular season, thereby eliminating the possibility for a game to end in a tie.
The NHL made another rule change in 2015, as overtime was reduced to three-on-three in the regular season.
Throughout the years, some teams have found a lot of success in OT, while others have struggled. Let's take a look at the unlucky teams.
5 NHL teams that suffered the most overtime losses
#5, Calgary Flames 2022–23, 17 OT losses
In 2022–23, the Calgary Flames had a staggering 17 overtime losses, which is the fifth-most of all time.
Calgary went just 7-17 in OT games that season, which played a role in the Flames barely missing out on the playoffs.
#T-1, Tampa Bay Lightning, 2008–09, 18 OT losses
The next four teams are all tied at 18 OT losses, but the 2008–09 Tampa Bay Lightning held the record for a couple of years.
Tampa Bay finished the year with a record of 24-40-18 and failed to make the playoffs in a disappointing season.
#T-1, Florida Panthers, 2011-12, 18 OT losses
The 2011–12 Florida Panthers tied the Tampa Bay Lightning's record for 18 overtime losses.
Despite dropping 18 games in overtime, the Panthers finished 38-26-18 and won the Southeast Division. Florida lost in seven games to the New Jersey Devils in the first round of the playoffs, who went on to reach the Cup Final.
#T-1, New Jersey Devils, 2013-14, 18 OT losses
The New Jersey Devils tied the record in the 2013–14 season, losing 18 times in overtime.
New Jersey finished the year with a record of 35-29-18 and failed to qualify for the playoffs. The Devils missed out on a playoff spot by five points, which they would have gotten had New Jersey not lost so many games in overtime.
#T-1, Philadelphia Flyers, 2014-15, 18 OT losses
The Philadelphia Flyers were the latest NHL team to tie the record in 2014–15, as the Flyers lost 18 times in overtime.
Philadelphia went 33-31-18 and missed out on the playoffs by 14 points as the Flyers struggled throughout the year.
