Yeah, maybe it was *reasonable* to anticipate a regression from 6th in the league with 109 points down to 10-12th with around 100 points, but nothing was there to indicate they were going to implode like this.
Goals for last year as 3.96 per game, this year is 2.58.
Goals against last year was 3.17 per game, this year is 4.17.
So goal differential has swung from +0.79 to -1.59 per game.
A -2.38 goal differential per game difference with largely the same players that had this group at 109 and 104 points the previous 2 seasons, and on pace for 105 and 97 in the 2 shortened years before that.
McDavid dropping from 153 points last year to like 120-130 this season would be a "reasonable" expectation, not all the way down to 80-something.
And there's no logical reason for the entire team defense (which was never amazing, but was at least serviceable the past few years) to totally shit itself, AND both goalies to do the same.
