Florida has given up 262 goals, third-most in the NHL. Only the Ottawa Senators (277) and Chicago Blackhawks (271) had allowed more.
The Panthers have had their share of injuries, including to forwards Vincent Trocheck (ankle, missed 27 games), Derek MacKenzie (shoulder, missed 76 games), Jamie McGinn (back, missed 59 games), and goalies Roberto Luongo (knee, missed nine games) and James Reimer (lower body, missed five games), but Barkov said the issue cuts much deeper than that.
"We've had a lot of guys hurt," he said. "At the same time, the guys who played, well, we didn't play that well. (Specifically) we didn't play that well in the defensive zone. We can score but our issues are in the defensive zone. We have to learn how to be better at that."
Scoring wasn't a concern for the Panthers. Five players scored at least 20 goals -- forwards Barkov (34), Mike Hoffman (35), Jonathan Huberdeau (25), Evgenii Dadonov (25) and Frank Vatrano (23); five have at least 50 points -- Barkov (88), Huberdeau (84), Hoffman (69), Dadonov (63) and defenseman Keith Yandle (58).
It's on defense where the Panthers struggled. Seven Panthers have a double-digit minus rating: defenseman Mike Matheson (minus-27), Hoffman (minus-25), Yandle (minus-19), Huberdeau (minus-18), forward Henrik Borgstrom (minus-14), Dadonov (minus-12) and Barkov (minus-11).
Coach Bob Boughner said Barkov is the last person who should receive blame for the Panthers' shortcomings. From the moment Barkov was named captain prior to the season, he's been Florida's best player according to Boughner.
"He's been amazing," Boughner said. "At the beginning of the season, putting the 'C' on him was a big change for him. But he's matured into the role. He's learned. And he'd be the first to tell you he's still learning.
"He's still a young guy but he's definitely led by example. When [Trocheck] was out, we struggled, and he carried us. Three months of that. Once [Trocheck] came back at the break and got healthy, you could see Bark's game take off the other way. I think he's turned the corner where he's always been a good offensive player but now you see he's an elite offensive player now."
