Rowe said the initial thought was to keep Gallant on through the end of Florida's current six-game road trip, which continues at the Chicago Blackhawks on Tuesday (8:30 p.m. ET; CSN-CH, FS-F, NHL.TV), but the loss at Carolina on Sunday sped up the decision by owner Vincent Viola to fire Gallant.
The Panthers lost after allowing three goals and getting outshot 13-7 in the second period against the Hurricanes.
Viola and Rowe informed Gallant and Kelly of the decision.
"After we collapsed in the second period [Sunday] night, it came to a head a lot quicker," Rowe said.
Rowe said he met with the players Sunday night. He met with assistant coaches Scott Allen, Dave Barr and Robb Tallas Monday morning and was planning to meet with Florida's leadership group, including captain Derek MacKenzie and alternate captains Aaron Ekblad and Jussi Jokinen, on Monday afternoon.
The Panthers had a day off in Chicago on Monday. Rowe said he will hold a full team meeting Tuesday before the game against the Blackhawks.
"I've got to lay out what our plan is and how we're going to do things differently," Rowe said. "The reason the players loved Gerard so much is he treated them with respect, he held them accountable. I'm not too much different than that. I think anybody wants to be treated with respect, and when you treat people with respect, you get the respect back. That's what we're going to do as a coaching staff and that's what we plan to do moving forward."
Rowe admitted there was a philosophical divide between management and Gallant for how the Panthers are built to play and how the executive staff believes they should play. He said that did play a role in the decision to fire Gallant.
The Panthers' moves last summer illustrate the divide. They signed mobile defensemen like Keith Yandle and Jason Demers and traded Dmitry Kulikov and Erik Gudbranson, who are more physical defensemen in the mold of what Gallant wants on his roster.
"We wanted to develop a team and build a team that was fast, could move the puck quickly, attack the offensive net, pressure the puck in all three zones," Rowe said. "Gerard and I talked about it and he said he wanted to get a little more size, and we decided to go in a different direction.
"Were we on the same page every day of the week? No, when it came to that. The best way to tell you is the philosophy was different and that did weigh into the decision."
