How should look like a goalie stats, if they want to match McDavid?
I think there 2 ways to look at it:
1) An gross evaluation on how much goal created over the nhl average first line center McDavid, what save percentage does a goaltender need when playing a lot of games to save that many goal versus the average starting goaltender. or it can above replacement player has well.
2) How it rank among center first line performer all-time versus how it rank among goaltender.
The top 31 center excluding McDavid this year scored an average 50.26 points, McDavid double that for 105 points, according to hockey reference he created 37 goals.
The top 30 goaltender this year averaged 977 shot against and let in 87.5 goals, .9104 save percentage.
If you want a goaltender to save 40 goals or so you probably want to play enough to receive 1,400 shots and give away only 86 goals (.939 save percentage)
Tim Thomas/hasek peak over a high volume in this current high scoring environment could be similar if that Hockey reference goal created estimate is good.
If is 55 points above the average first line center created closer to say 50 goals in reality that would be having .946 while playing 47-48 games on a team that receive a lot of shots
