I think this is a league wide problem right now.
I break it down at a high level like:
- There were rules changes which have made goal-tending harder.
- As a result, goaltenders are letting in more goals, and conversely players are scoring more goals.
- Players feel they are doing better than ever because of their higher output.
- Goaltenders are looking bad because more goals are going in.
Humans are not good at seeing how these big “on average” trends are related, and stem from the rule changes. Especially when trends are obscured at the individual level by the normal year to year variations in performance.
The challenge for teams is to avoid this hurting their locker-rooms.
