If trouba doesn't want to leave NYR then all he and his agent need to do it's build out his nt list to tie Drury. It's not that hard to id 16 teams throughout the league that probably wouldn't trade for him anyways. So all he needs to do is add the 15 other teams to his list that might trade for him and then Drury is locked.
If trouba doesn't want to be traded he just submits a list like this
Ntc Anaheim
Boston
Ntc Buffalo
Ntc Calgary
Carolina
Ntc Chicago
Colorado
Ntc Columbus
Dallas
Ntc Detroit
Edmonton
Florida
Los Angeles
Minnesota
Ntc Montreal
Ntc Nashville
New Jersey
NYI
Ntc Ottawa
Ntc Philadelphia
Pittsburgh
Ntc St. Louis
Ntc San Jose
Seattle
Tampa
Ntc Toronto
Ntc Utah
Ntc Washington
Winnipeg
Vancouver
Vegas
I've virtually landlocked him into staying in NYR by accounting for teams available cap space for his contract, team need for the position, team focus on analytics, and just using a brain about who would/wouldn't actually add him (like Winnipeg isn't trading for him).
Sure a waiver claim is possible, but it's extremely low probability. I'm not sure that the team has the type of leverage or control of this situation that you're projecting. The only thing that's certain is that this is becoming a circus, and a very public circus at that
