Florida received Hoffman and a seventh-round pick in the 2018 NHL Draft from San Jose for a fourth-round and a fifth-round pick in 2018 and a second-round pick in the 2019 NHL Draft.
San Jose acquired Hoffman from Ottawa, with defenseman prospect Cody Donaghey and a fifth-round pick in the 2020 NHL Draft, for forward Mikkel Boedker, defenseman prospect Julius Bergman and a sixth-round pick in 2020.
Luongo said he had no concerns about Hoffman's impact on the Panthers' locker room chemistry. The Ottawa Citizen reported last week that Melinda Karlsson, the wife of Senators captain Erik Karlsson, filed an application for a peace bond against Hoffman's girlfriend, Monika Caryk, alleging harassment and cyberbullying that occurred this season and continued after the Karlssons' son, Axel, was stillborn. Hoffman has denied the allegations.
"We've heard some good things about him as a person and a player and we've got a really strong locker room, a great bunch of guys, and I'm sure he'll fit right in," Luongo said. "We'll welcome him, and I'm not worried about that stuff. I think it will take care of itself. But the fact that our group is so strong and close-knit, I think, it will work out well."
The Panthers were 14th in the NHL this season at 2.99 goals per game. Hoffman scored at least 26 goals each of the prior three seasons with Ottawa before scoring 22 this season.
"He's a great player," Barkov said. "He can score goals, everybody knows that. So I'm excited to have him on our team and looking forward to him playing for us and scoring goals."
