It's these.
I don't buy the idea that Igor is "the real issue". He's very clearly not playing at his Vezina best, and he's not winning us games, and that's one of many issues. Over the last few weeks, the goalies have been hung out to dry by absolutely hideous team defense. There's only so much a goalie can do when you continuously let the best players in the world take free shots from the slot, whack away to or three times on rebounds, stickhandle unchallenged around the crease and come in on multiple odd man rushes and breakaways.
Yeah, an Igor at his best makes some of the saves he hasn't made lately. And he might even steal a couple of the games we've lost. But relying on goaltending to steal games is not a viable strategy.
This is not a defense of Igor in any way, because he's unquestionably not anywhere near his best, but I think describing him as "the" issue is missing the forest for the trees.
