The Flames have never had a Norris Trophy winner.
"It always feels good to contribute and get points offensively, but again, we have such a good team, we score so many goals that a lot of guys' numbers are going to look really good this year," Giordano said.
Giordano helped the Flames tighten up defensively this season and is a big reason they finished second in the NHL with a plus-66 goal differential.
"It's every night," Peters said. "Each and every night. He's in on all of the big plays. ... You've seen it all year, and he just continues to play at a high level."
Giordano averaged 24:14 of ice time per game to lead Calgary. He plays in all situations; Giordano had 21 power-play points and six shorthanded points (four goals).
But he didn't take credit for the Flames' success this season after they missed the Stanley Cup Playoffs in 2017-18.
"We've been pretty consistent all year," Giordano said. "Our style of play and our details is what helps us every night. We have a lot of depth."
