The Lightning joined the Montreal Canadiens (1976–1980) and New York Islanders (1980–1984) for becoming the only teams in league history to post at least eleven consecutive playoff series victories.
During the off-season, the Lightning signed goaltender Brian Elliott, defenceman Zach Bogosian, and forwards Pierre-Edouard Bellemare and Corey Perry via free agency.
[24][25] For Corey Perry, this was his third straight Finals appearance with three different teams (Dallas Stars in 2020, Montreal Canadiens in 2021), the first player to accomplish this feat since Marian Hossa did it with the Pittsburgh Penguins in 2008, Detroit Red Wings in 2009, and Chicago Blackhawks in 2010.
[37][38][39] Nearing the trade deadline, the Avalanche acquired Josh Manson, Nico Sturm, Artturi Lehkonen, and Andrew Cogliano.
Colorado's captain Gabriel Landeskog began the scoring, pushing the puck past Lightning goalie Andrei Vasilevskiy when Mikko Rantanen's shot barely squeaked under the goaltender's pads.
[48] The next goal came when defenceman Victor Hedman's clearing attempt got picked by Nathan MacKinnon, whose pass to Valeri Nichushkin made it 2–0.
[49] The Lightning halved Colorado's lead when Brayden Point's dump-in was retrieved by Nick Paul who broke in and dangled out Avalanche goaltender Darcy Kuemper to make 2–1.
[52] 1:48 later, the Lightning continuing their offensive zone attack had a pass back to Mikhail Sergachev from Brandon Hagel whose shot through traffic went off the post and into the net.
[55] The puck then came to Nichushkin who passed to Andre Burakovsky and he fired a snap shot past Vasilevskiy to give Colorado a 4–3 victory.
During it, Andre Burakovsky led a cross-ice pass to Valeri Nichushkin's tip-in goal to give the Avalanche an early 1–0 lead.
The Avalanche then grabbed a 2–0 lead when a 2-on-1 rush with Andrew Cogliano and Josh Manson led to the latter's wrist shot under Andrei Vasilevskiy's blocker.
In the second period, the Avalanche continued their offensive zone coverage allowing Rantanen to centre a pass to Nichushkin to make it 4–0.
The Avalanche then made it 5–0 when the Lightning misplayed a pass leading Darren Helm and Logan O'Connor on a 2-on-1 break for which the former's wrist shot went over Vasilevskiy's glove.
In the third period, as Rantanen was in the penalty box for tripping, the Lightning gave the puck away to Cale Makar who, with Andrew Cogliano on another 2-on-1, made it 6–0.
After a coach's challenge revealed Valeri Nichushkin's goal was offside, and then Ondrej Palat got called for high-sticking, Colorado went on the power-play.
During the power-play, Cale Makar set up Mikko Rantanen for a quick shot through traffic which pinballed off Andrei Vasilevskiy and Erik Cernak for an easy tap-in for Avalanche captain Gabriel Landeskog.
The first goal came off a turn-over from Colorado's Josh Manson who gave the puck to Victor Hedman setting up an open Nick Paul for a 3–1 lead.
Although the third period had no goals scored, both teams leveled their frustration at each other with both Logan O'Connor and Ross Colton fighting and Patrick Maroon and Andrew Cogliano both squaring off after the whistle resulting in misconducts.
Tampa Bay regained the lead as defenceman Victor Hedman led the rush into the offensive zone, slipping by the defenders, and backhanding a shot over Kuemper for 2–1 advantage.
In overtime, Kuemper flipped the puck ahead to Artturi Lehkonen who passed to a speeding Nazem Kadri who got the shot through Vasilevskiy and into the top part of the net.
The Avalanche, upon winning a faceoff, had Nathan MacKinnon pass to Cale Makar who shot the puck at Andrei Vasilevskiy but the rebound bounced to Valeri Nichushkin for an easy tap-in goal.
As the Lightning were working the forecheck, a giveaway by Cale Makar brought an errant deflection to Steven Stamkos who put it five-hole through Darcy Kuemper.
The Avalanche managed to tie the game in the second period during their offensive zone coverage which led to a delayed penalty on Tampa Bay.
