Prior to Tom Wilson’s return to the lineup, the Capitals had the third-worst PK in the league, both in overall percentage and in terms of goals allowed per sixty minutes of shorthanded time; since his return they have the third best. It’s easy to assume that one has been influenced by the other - but as we all know, correlation doesn’t necessarily equal causation.
So let’s look at a few different metrics to determine whether the penalty kill is better now than it was before...and maybe if it was ever even bad in the first place.
