Should any of these be considered as “what the hell happened losses? Or more the product of a strong league?
Both and neither.
Seasons are designed to win a league, place in a conference, a division. Seasonal standings reflect this. Schedules are never balanced ideally. Teams can play for a tie or the "loser point".
Playoffs, in the NHL this usually has meant a 4 out of 7 format since the start of the O6 and a bit before. Each series schedule is balanced in terms of travel and off days. Same opponent, each team has to play for a win every game. Regular season weaknesses can no longer be hidden like they can by juggling line-ups and rotating players.
Major difference is that today a team does not get a 14 game RS preview of a potential playoff opponent. So your RS point differential reflects an ability to play within a league not your ability to play the opponent you may ace in each round of the playoffs.
