The Kraken (24-12-4) - in the midst of a seven-game, 13-day road trip - have won six consecutive games to start the month of January, including back-to-back victories over Montreal (4-0) and Buffalo (4-3) on Monday and Tuesday.
Seattle, now in its second NHL season, ranks third in the league in goals per game (3.68) behind Buffalo (3.87) and the Bruins (3.85), though they sit in the middle of the pack (17th) in goals allowed per game (3.10).
"Really good hockey team," said Montgomery. "Really similar to Toronto, really similar to us. They reload, they are working as five guys really hard, they forecheck well, they defend well, they're a zone defense, they break pucks out well. They're doing a lot of really good [things].
"They're the No. 1 5-on-5 scoring team in the league. That shows they have four lines that can go. The defensemen are No. 1 in the league in scoring. We've got a great challenge ahead of us tonight with them."
The Kraken are paced by Andre Burakovsky who is the club's top scorer with 35 points (11 goals, 24 assists) in 40 games. Jared McCann leads the Kraken with 19 goals in 37 games. Former Bruins forward Ryan Donato has eight goals and 13 points in 33 games.
Rookie Matty Beniers (he played just 10 games last season), meanwhile, has burst onto the scene this season and is second on the club in points (34) and goals (16). The Hingham, Mass., native also leads all rookies in both of those categories.
"He's a really good hockey player," said Montgomery. "He's as good defensively as he's shown offensively. He might even be better defensively. His reads in the D-zone, trakcing, and then on the forecheck are high end. I don't want to compare him to Bergy, but you see some of those qualities the way he plays without the puck."
Martin Jones has carried the load between the pipes with a 19-5-3 record, 2.78 goals against average, and .894 save percentage.
