What do shot rates have to do with goals against? Klefbom consistently gives up a lot of goals against. He consistently has a sub par on ice save % because he consistently makes mistakes in his own end leading to chances.
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.
