In Sergachev, Cirelli and Cernak, the Lightning have locked up a defenseman with top pair potential, an excellent defensive center and a good right-shot defenseman, all needed pieces as they try to stay among the best teams in the NHL.
Sergachev, 24, had 38 points (seven goals, 31 assists) in 78 games last season and 10 points (two goals, eight assists) in 23 playoff games. Cirelli, also 24, had 43 points (17 goals, 26 assists) in 76 regular-season games and eight points (three goals, five assists) in 23 playoff games. Cernak, 25, had 13 points (one goal, 12 assists) in 55 regular-season games and two points (one goal, one assist) in 23 playoff games.
"It's great to see him keeping the core together," Sergachev said. "It means a lot to me as a player. Obviously, I want to win. I want to play for the best team possible. He's providing that every year. He's a great GM."
It was a common feeling.
"For [Sergachev and Cernak] to get that as well, very happy knowing that they'll be here for another eight years as well, kind of keeping those guys together," Cirelli said. "We all came in kind of at the same time. It's nice to go through this process with them, know we have each other."
It was clear that BriseBois was committed to this younger core after he traded defenseman Ryan McDonagh to the Nashville Predators on July 3. It was a move that opened both playing responsibility and cap space for the deals that followed on Wednesday.
The idea was that Sergachev was ready to assume some of the role that McDonagh had previously held. It was a show of faith in him and his game.
"It means a lot," Sergachev said. "I've been waiting for more responsibility."
Brisebois made two other signings on Wednesday, adding forward Vladislav Namestnikov and defenseman Ian Cole to a one-year contract each.
But the real prizes were the trio of players who will now settle in for a stay in Tampa until at least the 2030-31 season, with the expectation that they will be playing a lot of playoff hockey between now and then.
"You go down the list with Point, Kuch, Stammer, Heddy, Vasy back there," Cirelli said. "As long as we have those guys, I think we'll be good for a long time."
