Well, Oiler fans have originated many of these stats. PDO and Fenwick, for instance. But they have generally proven out to be fairly representative.
So an Oilers fan can look at those stats and say "we should be better" all they want, and that is fair comment. But we all know what should happen on paper and what does happen on the ice don't always correlate perfectly. And certainly in terms of possession stats, you can look good in that one aspect but lose frequently because your goaltending and/or offence sucks. That is the case in Edmonton.
