Good news there.
PP has been much better. PK is a concern, but they don't take a ton of penalties so that helps.
Goaltending is a massive concern long term that they can't do much about. We'll see how it shakes out.
Faceoffs are are massive concern long term that we can only hope they can somehow get up to 49ish percent by the end of the year.
Gophers have given up the first goal in exactly half of the games so far. They're 6-1 in those games which feels pretty crazy. If they can fix that, it'll only help. Would love to see them get the first goal in 5 of the next 6, considering the Alaska games should be first goal both games.
Minor improvements across SV%, FO%, and PK% would likely have them in a place to make a run come tourney time.
As far as "advanced stats", I think those are garbage and geeky people trying to justify themselves in the hockey world most of the time. This is coming from a numbers person.
