I'm just sitting here and wondering, why seemingly every team in the NHL has the worst goaltender? There are just too many threads
It's probably the new equipment size regulations. It seems to have exposed a ton of goalies. For example by GSAA:
Raanta, 2017-18 was 24.82 GSAA, and 2018-19 is 0.20 GSAA
Hellebuyck, 2017-18 was 23.75, and 2018-19 is 0.45
Fleury, 2017-18 was 20.77, and 2018-19 is 2.09
Crawford, 2017-18 was 13.9, and 2018-19 is 2.23
I left out some goalies who didn't have a reasonable amount of games this season.
And if you check the reverse - goalies that are fairly equal or better than last season:
Rinne, 27.49 and 13.77 (the highest GSAA of goalies this season)
Gibson, 25.30 and 11.41
Vasilevskiy, 15.12 and 7.59
Andersen, 12.06 and 13.38 (one of the few to have better GSAA than last year!)
Varlamov, 11.99 and 7.88
So, relatively speaking, Andersen has been the best goalie this season, so far. Followed by Rinne and Gibson, who have suffered - especially relatively - compared to their last season.
Edit:
Oh and speaking of Reimer:
2017-18 GSAA: 0.51
2018-19 GSAA: -4.89
So definitely average
