The more I think about it, the more I think we're up shit creek if we don't get at least Muzzin back. The Kings were strong down the stretch because of Carter, but also because they had almost everyone healthy for about 5 total games before Lewis got banged up again. Iafallo's a bigger piece than people will give him credit for. But the bigger problem is that there's no one to go to on D in big situations towards the end of the game with those two guys out.
Doughty-Muzzin / Phaneuf-Martinez / Folin, Forbort is MUCH stronger than Doughty-Phaneuf / Martinez-Folin / Gravel, Fantenberg, LaDue. Those guys will get gassed in short order AND without significant benefit if we have to shorten the bench like that (and Stevens does like to do that late in the third, you'll see Doughty-Muzzin / Martinez-Phaneuf inoffensive situations, Doughty-Phaneuf / Martinez-Folin in defensive).
That's something Vegas' depth will exploit at will.
