Daniel Alfredsson was right.

A day after Ottawa's longtime captain caught fire for remarking his team could "probably not" come back against the Penguins -- out of context or not -- they certainly did not.

In the end, it was the Penguins' skill laced throughout the lineup that proved insurmountable. Ottawa lost Game 5, 6-2, and the series, 4-1.

Is it the deepest Penguins team he has seen?

"It's hard to say because we've been in different situations with ourselves," Alfredsson said. "But they were a class above us."

Ottawa goalie Craig Anderson, said unequivocally, they are.

"I don't know if I've ever seen a team that deep to be honest," Anderson said. "Maybe pre-lockout when there wasn't a salary cap? But like I said, star players doesn't mean you're going to win. It's how they come together, play as a team.

"They're well-coached over there. They work well together. Everyone is pulling in the same direction on the team and it shows."

Ottawa's locker room was packed up and cleared out just minutes after the final horn, but several players trickled back in to talk about what went wrong.

"We lost to a better team," defenseman Marc Methot said. "You've got to give them props over there. They outplayed us. They're a better hockey club. That's the difference."

Alfredsson, who said he hasn't yet thought about what's next for him, said the Penguins' next opponent will be hard-pressed to make it past them.

"I think if Boston would win [tonight] they're a team that's really strong defensively. You look at Pittsburgh they would be the favorite," Alfredsson said. "They have skill, speed, well-coached. They're going to be a tough team to beat."

The Senators' only win in the series came at home in a second overtime period in a game the Penguins' power play was snakebit.

By midway through the second period in the elimination game Friday night, the Penguins had built a 4-1 lead on goals by Brenden Morrow, Kris Letang, James Neal and Evgeni Malkin.

The Senators made a last-ditch effort to extend the series by opening with their three best forwards together on the top line: Jason Spezza at center with Milan Michalek on the left wing and Alfredsson on the right.
