Colton Sissons gave Nashville a 4-2 lead on a breakaway at 7:40 of the second period, which prompted Florida coach Paul Maurice to pull Bobrovsky.
"I got [Bobrovsky] out of there because I didn't think it was going to be goaltending deciding the game," Maurice said. "For us, he's played a lot of hockey. It's an awful lot for him, so give him a little bit of rest and give Spencer some work."
Josi made it 5-2 at 16:23 with a slap shot from the left face-off circle that beat Knight high to the glove side.
Novak gave the Predators a 6-2 lead with a power-play goal at 8:58 of the third period, banking a shot off Knight from behind the net. It was the first two-goal NHL game for Novak, who was a healthy scratch for two games before returning against the Bruins.
"Sometimes a game off or two isn't the worst thing for guys," Hynes said. "They come back in, they're energized, refreshed and ready to go. He was good. He's a guy in particular where against Boston, he really wasn't himself. He's a guy that has great poise with the puck and makes plays when he has time and space. He was one guy in particular we talked with, and tonight you see the difference in his game."
Reinhart cut it to 6-3 with a power-play goal at 9:48, but Yakov Trenin scored an empty-net goal at 14:14 for the 7-3 final.
