Restricted free agency and offer sheets continue to be unentertaining and non-existent in the NHL. Other professional sports leagues don’t neglect the restricted free agency market like NHL continues to do.
At this point, RFA’s are not even free agents. There’s no fear of another team coming in to swipe a player off the roster. Thus the player is forced into team-friendly contract more often than not.
It’s not surprising that a league that seems to go out of its way to remove entertainment from its game on the ice (see offside and goaltender interference challenge) would do the same in other areas as well.
