Correlating on-ice save percentage to defensive acumen doesn't really pass the smell test. Very often heavy minute defenders have worse on-ice save percentages than lesser defenseman in different roles.
For example, the two worst LA Kings in on-ice save percentage >50 games in 17-18 were Drew Doughty and Anze Kopitar. Are they defensive tire fires?
If the contention is that Oscar Klefbom allows more higher danger scoring chances against, which lowers the expected save percentage of a goaltender, that correlation can be checked on.
Larsson: 3.76 high danger chances against/game
Nurse: 3.64 high danger chances against/game
Klefbom: 3.35 high danger chances against/game
Russell: 3.22 high danger chances against/game
Benning: 3.14 high danger chances against/game
My view on Oscar Klefbom is that he makes obvious errors which is understandably frustrating, but usually not a huge deal. Normally that's canceled out pretty well by the fact that the Oilers have been significantly more productive with him on the ice than without in almost all regards throughout his entire Oilers career. This past year not so much. Lots went wrong last year that I doubt continues to go wrong and that's pretty high on the list of things I think will be different.
Klefbom fails the eye test very very obviously defensively and outside of maybe a total of 82 games has ALWAYS failed the eye test very very obviously. A full on defensive defensman like Larsson is required to make up for his poor defensive play. As well as stellar goaltending.
It's not coincidence that when Klefbom has one of his painfully terrible brain farts the puck ends up in the back of our net. Its not bad luck/on ice save percentages. Its simple cause and effect.
He has shown the ability to play at a top 3 level defensively/offensively. But it's been very inconsistent and when he isn't there it's so obvious imo a blind man can see it.
Apologies for the rant but it drives me crazy that so many look past/make excuses for his often terrible play.
I want the guy to succeed. He has shown he can. But when he is failing just call it as it is. No reason to suger coat it.
