Bennett scored five points (one goal, four assists) in five games in a six-game loss to the Tampa Bay Lightning in the Stanley Cup First Round. He was suspended for Game 2 by the NHL Department of Player Safety for boarding Lightning forward Blake Coleman.
Selected by Calgary with the No. 4 pick in the 2014 NHL Draft, Bennett has scored 155 points (73 goals, 82 assists) in 412 regular-season games for the Panthers and Flames and 24 points (12 goals, 12 assists) in 35 Stanley Cup Playoff games.
"Sam's impact on our club this past season was seen immediately, injecting physicality, skill and energy into our lineup," Panthers general manager Bill Zito said. "We are thrilled to have him in our Panthers lineup and look forward to what he can bring to our offense in the upcoming 2021-22 season."
Forward Sam Reinhart was traded to the Panthers by the Buffalo Sabres on July 24, giving Florida three of the top four picks from the 2014 NHL Draft: Reinhart (No. 2, Sabres), Bennett and defenseman Aaron Ekblad (No. 1). Three other Panthers were chosen in the top 10: forwards Aleksander Barkov (No. 2, 2013), Huberdeau (No. 3, 2011) and Tippett (No. 10, 2017).
"Right away when I saw [the Reinhart] trade, I actually texted 'Huby' right away and we were both super excited about that, and then I reached out to 'Reino,'" Bennett said. "I know him a little bit from the draft and growing up playing hockey. Getting a great player like that, it just shows how much this team is ready to win and committed to winning. It makes me so excited to get the season started, and my confidence for this team is through the roof right now."
The Panthers (37-14-5) were the No. 2 seed in the Discover Central Division, one standings point behind the No. 1 seed Carolina Hurricanes. Florida has not advanced in the playoffs since going to the Stanley Cup Final in 1996.
"I think we're very close, and now with some of the moves we're making, I think we're getting even closer," Bennett said. "We have a really good team that just seems to be getting better and it's going to be a fun year, that's for sure."
