Kevyn started it by giving Samson a second bridge deal, only one year. That was the signal that another rebuild was in the offing, that was why Jack wanted out. The neck thing was the justification and was exploited by both sides to make his trade inevitable, but Jack didn't want to be part of another rebuild and not locking up Sam was the first shoe to drop, not Eichel wanting out. Reinhart was essentially kicked off the team by Kevyn.
Tage will be next. He'll want out.
