Finding Hyman
What the stat shows is that if McDavid and Draisaitl regress to 1.0 ppg pace, or even a 1.5 ppg pace, the Oilers are going to start losing their fair share of games. While I would be thrilled if McDavid scored 150 points this season, I think most of us can agree that it is unlikely to happen. What the stats tell us is that the Oilers are getting killed at even strength right now, so when the PP normalizes to a more sustainable percentage, the team may be in trouble. Same goes for both goalies currently stopping pucks at a higher percentage than usual.
HDSC is useful in my opinion because most goals are scored from close to the net. So if you give up a ton of those, then over the course of the season you're probably going to give up more goals. Winning 4-5 games while getting out-chanced significantly means you better fix that aspect of your game up before McDavid and Draisaitl slow down.
That said, if McDavid scores 150+ points, it probably won't matter what the advanced stats say.
This isn't true either because the Oilers aren't going to finish the season with a ten players with zero boxcars. Nuge is also going to score more often than one in 7gp. Scoring can balance out a bit.
Further for McD to exceed 1.5pts/game is certainly plausible. He's in prime of life and is that good a player. A player as normal as Kucherov had 128pts last season. On that basis of comparison I would say a 150pt McDavid season at some point is plausible. People are forgetting the player keeps getting better, has a generational sidekick to play with, and the sky is the limit. McD potential is hard to nail down. now that we have better schemes, transition, and D support the offense is headed up for a reason.
