Skater talent has greatly increased over the past decade while goaltending has gotten steadily worst. Kids growing up in the 90's and 00's wanted to be Brodeur, Hasek, Roy, Luongo, Cujo, Belfour, etc. But kids who grew up in the 2010's grew up wanting to be McDavid, Crosby, Ovechkin, Pat Kane, etc.
The goalies of the late 00's and '10s were boring, just giant pad monsters with little flair or excitement. It made the position seem very boring, while the skaters were doing things that had never been seen before. Obviously there were some exceptional goalies during this time, but most didn't feel very fun to watch.
All of the young athletic talent is going into skaters and very little is going into goaltending these days. Goalie development is fickle enough as is, now factor in loss of playing time due to the pandemic and it's going to get worse before it gets better. Kids can practice stickhandling in their garage, but goalies can't simulate stopping pucks without actually playing the game. Juggling tennis balls only does so much.
GMs are also getting far more cautious with goalie contracts these days. There is far more money to be made being a star forward/defenseman as opposed to a star goalie. Guys are pretty routinely getting 6-7M AAV on their second deal at 21-23. A goalie today might not ever get an AAV that high in their career, and if they do it will be on a 3-5 year deal after they turn 25.
So it's not surprise. Skater talent has gone through the roof and goaltending talent has collapsed.
