Calgary cut its goals against from 2.86 per game last season to 2.51 this season and allowed the third-fewest goals (206) in the NHL. That was the best defensive performance of any Western Conference team and included an NHL-low 139 goals against at 5-on-5 this season.
No. 1 goalie Jacob Markstrom (37-15-9 in 63 starts, 2.22 goals-against average, .922 save percentage, nine shutouts) led the way.

Markstrom allowed two or fewer goals in 39 starts this season, and his nine shutouts led the NHL.
He was also a major factor in Calgary's record in locking down games. The Flames were 40-1-2 when leading a game after two periods, best in the NHL.
With that kind of defensive foundation set, the Flames should have no difficulty adapting to the grind of the Stanley Cup Playoffs and adding the 2022 banner to the 1989 banner that hangs in Scotiabank Saddledome.
Their style is well-rehearsed and the required adjustments should be few under veteran coach Darryl Sutter, who was hired midway through last season, March 4, 2021.
Calgary's reliable game this season, which included an average of 29.0 shots against per game, fifth-lowest in the NHL, helped them to the best road record in the Western Conference (25-12-4), another integral rehearsal for the playoffs, where winning on the road is essential.
The surprising element to Calgary's championship run this season may be the offense that comes from solid defense. The Flames struggled to score last season, 2.77 goals per game, which was 20th in the NHL, and Sutter said repeatedly that scoring easily was just not in the team's DNA. This season, Sutter made the same claim but production increased to 3.55 goals per game, sixth-best in the NHL.
