"There's some progress there," Panthers coach Joel Quenneville said. "I think consistency is something that we stressed coming into the season, that our start was going to be very critical to what's going to happen at the end. We've played some good opponents, and there's been some good signs."
Improving his own record on the season to 3-0-0 with another stellar performance, Bobrovsky earned the 300th win of his NHL career, becoming just the 38th goaltender to hit that lofty mark.
"It definitely means something," said Bobrovsky, who's won 55 games over parts of three seasons with Florida. "I've been fortunate to play with great players, with great defensemen, forwards and teams. I appreciate them for this milestone. I had fun playing in the game."
Opening the scoring for the fourth straight game, the Panthers jumped out to an early lead when Mason Marchment won a footrace for a loose puck at the end boards and then shipped a pass to Sam Reinhart for a goal right outside the blue paint to make it 1-0 at 14:32 of the first period.
Pulling the Avalanche even with just 53.9 seconds remaining in the first period, Mikko Rantanen swept a rebound past Sergei Bobrovsky after a shot from Samuel Girard to make it a 1-1 game.
Only two games removed from scoring a hat trick, Sam Bennett put the Panthers back on top at 9:04 of the second period when he beat Jonas Johansson, who was blinded by a perfectly set screen from Patric Hornqvist, with a shot from the slot on the power play to make it a 2-1 game.
Extending the lead with less than a minute left to go in the middle frame, Carter Verhaeghe gathered the puck along the half-wall, skated into the slot and scored to make it 3-1 at 19:13. Filling up the net, Florida has scored a franchise-record 18 goals in its first four games.
"Everyone's contributing," Bennett said of the offense. "That's the sign of a good team. It's a good feeling when everyone is getting on the board. We're just going to try to keep it rolling."
That would be all the goal support the Cats would need as Bobrovsky, a two-time winner of the Vezina Trophy as the top goalie in the NHL, stopped all eight shots he faced in the third period.
With 1:13 left in regulation, rookie Anton Lundell scored an empty-net goal to make it 4-1.
Earning the No. 1 spot on the NHL's most-recent "Super 16" power rankings, the Panthers, who posted the fourth-best record in the league last season, have seemingly picked up right where they left off and have gained control of first place in the Atlantic Division right out of the gate.
"We're having a lot of fun right now," Panthers captain Aleksander Barkov said. "Coming to the rink since Day 1, we've been working hard. Whether it's on the ice or at the gym, we like being around each other. We've just put the work in. … We've beat a lot of good teams so far."
Going for their fifth straight win, the Panthers will visit the Flyers on Saturday.
