Whatever Perry did was presumably not in dispute though - as it seems to have happened in front of team employees. He also still has time to file a complaint (and is expected to do so), so he still may collect on that contract.
With Galchenyuk - what he did was on video, so zero dispute there...whereas these are still allegations at this time.
Any NHL team would only be getting out of a contract roughly 2 months early at this point, so I really don't see it happening. Also not a great look if their player is eventually found not guilty. Where it may get interesting in the off-season is if any players are qualified in order to retain their rights or teams just let RFA contracts expire.
