Part of me is sympathetic to the personal side of this for Trouba. Just because you have a lot of money doesn't mean things are less stressful. His wife has probably worked insanely hard to get where she is in her field and having to potentially give that up cannot be easy. Add in the fact that they have an infant to take care of on top of that.
That being said, this is the reality of the business. Chris Drury's responsibility is not to Jacob Trouba; it's to do everything in his power to make this team into a Stanley Cup winner. When you have a guy making $8 million a year that is quite clearly not cut out to play more than 3rd pairing minutes against top teams, that is a MAJOR hindrance. As a professional athlete, Trouba had to account for the fact that he could be on the move once his NMC turned into a limited NTC if he was not up to the standard of play that the Rangers needed.
