Stu Skinner could be better than he has been, but, whatever, the Oilers just need average goaltending.
I have two concerns about Edmonton's chances of finishing off this series in game six (or seven, for that matter):
1) Darnell Nurse -- Nurse was utterly disastrous in games three and four (both in L.A.). Like, among the worst games of his career. The Oilers would have just won the series if not for Nurse's utterly awful plays in game three (the team overcame him in game four). He was much better in game five in Edmonton, but still had an inexplicable gaffe on the third Kings' goal. If Nurse can just calm down and play his position without reaching for pucks, doing the starfish, or trying for 'hero' plays at bad moments, he can be an excellent player. He certainly has the skills and size/toughness. The problem is that about every other game he falls into these terrible habits...
2) Connor McDavid's defensive game -- McDavid has generally been very good defensively this year (I mean, by the standards of a top-line center), and at times has been excellent. But for some inexplicable reason, he's been quite poor this series. He was awful defensively in game five. I don't know what's going on this past week or two, but he needs to be more dialed-in in his own zone.
If those two issues are adequately dealt with, the Oilers will eliminate L.A. in game six.
