Outside view (Bruins fan)
It's the players. At first it appeared that the lack of Price was the defining factor. Then perhaps that management had lost control of the room.
Either the non-core players are performing at actual ability and were over-performing before or they only play significantly better with Price in net. In either situation it is the players.
Keep the core and cut the fat that has identified itself.
Really, had they kept up a torrid pace of players over-performing, eventually the drop-off would have happened. Price would have made up for the shortcomings but the deadline would have passed and the problem would have identified itself leading into the playoffs when it was too late. Now there is an opportunity to make moves and turn things around. Blessing in disguise.
Having watched this MTL team, I know the core players very well and they share a common trait. They love the comeback and being the underdogs to spoil the party. Add an emotional Price return pre-playoffs into the mix and it's game-time. (Remember Koivu's return... I do) Fight your way back into the playoffs while we hold on for dear life ourselves. (Unlikely we maintain... Let's be honest.)
If we fail you need to snag that last spot and underdog the heck out of WSH. If I can't see BOS-MTL in the post season, the next best thing is to see an overconfident team get upset and then relentlessly flamed by a fan-base. Our historical differences aside, we can all agree that someone needs to take them down a peg and as a realist I don't think we can... But a re-adjusted, emotional MTL roster might be able to.
Now clean house and get back in the race.
