So having players injured was just a temporary situation which was bound to reverse itself in due time, but having an almost fully healthy roster... isn't?
What would lead anyone to believe that THIS group of players should be expected to get through a normal season without major injuries?
2012: "If we hadn't been missing Skinner and Pitkanen for so much of the season..."
2013: "If we hadn't been missing Ward and Pitkanen and half our other defensemen..."
2014: "If we hadn't been missing Skinner and Semin and Ward..."
2015: "If we hadn't been missing Jordan and Semin..."
That stuff is part of life in the NHL, but most teams don't fall completely to pieces and end up in last place when it happens. This team falls to pieces because the roster is below average to begin with and only gets worse when you start removing key components.
It's a part of life, but we had several major players injured for a long period of time, far and above what's normal in this league. Injuries happen, but no team is going to be able to deal with major injuries to Skinner, Jordan, Semin, Tlusty and Eric (who hasn't really been actually healthy until these last few weeks, despite playing) at the same time. If you take 4 of any team's top 6 out, including the top couple of centers, they're gonna crash and burn.
Most of those seasons had rosters that were worse than this one, and with fewer key injuries than we've had this half season through the whole season. Yes, injuries to key players happened, but not major ones and not all at once. When one or two major guys are out at any given time, you should expect that and have the depth to fill in. When you have your entire defense out (as happened a couple seasons ago), or almost all of your top six, as we had this season, those are not normal things, and those are not things that any team has the depth to handle well. Remember the 2012 Kings? A team that wound up winning the cup with the most dominant playoff performance in recent memory had a losing record early in the year, because they had a lot of key injuries. They recovered from it, got the 8th spot in the playoffs, and went on a run. That's not gonna happen to us, but that's a cup caliber team, and they didn't have the depth to keep winning with injuries that were actually less significant than the ones we had to start the season. As a comparison to a team everyone acknowledges to be very good, do you think Pittsburgh could win with Crosby, Malkin, Perron, and Kunitz all out? I don't. That's pretty much what we were dealing with earlier. A nightmare scenario.
Serious injuries can cripple otherwise good teams. Sometimes, you just have a string of s***ty luck, and the worst thing you can do is to overreact.
