It's something the Senators have seen before, and have exploited. By the middle of the first round against the Boston Bruins, the Senators were playing against non-regulars, with Boston having lost defensemen Torey Krug, Brandon Carlo, Adam McQuaid and Colin Miller to injury.

It's not quite that extensive in Pittsburgh, but Letang is out for the rest of the season after neck surgery and Daley remains day to day with a lower-body injury. Those are two major losses, perhaps the top two defensemen for the Penguins.
"I think our depth is our strength. We have a lot of good players," Maatta said. "We've been dealing with injuries all this season, last season, and we know there's always got to be the next guy who's going to step up. When somebody goes down, obviously it's unfortunate, but it's part of the game. You've just got to have those other guys step up."
But that becomes more difficult the further the Stanley Cup Playoffs progress.
"We think all of these guys are capable of helping us win games," Penguins coach Mike Sullivan said, noting the ability to shuffle the pairs as well. "Certainly [Letang and Daley] are difficult guys to replace. I think that I'm stating the obvious when I say that.
"But certainly we believe as a group we have a capable group back there that can step in and play a solid game for us, and that can help us continue to play and establish the type of game that we want to play that gives us the best chance to win games. And that's our expectation, I think that's the message that we send to our group."
