Let's play a game. Let's find a team that won't be on Trouba's NTC AND would have an interest in him. Lots of assumptions coming but here goes.
I assume based on prior history that Trouba will block any trade to Canada. That's 7 teams (MTL/OTT/TOR/EDM/WIN/CAL/VAN) right off the bat. Leaving 8 spots left for him to block. My hunch is that he will ALLOW trades to any Metro team, because I dont think the Rangers would ever trade him in division (MAYBE Columbus because of the Davidson connection).
That leaves 17 teams. VGK/COL/MIN/STL/BOS/FLA/TBL all look to me like teams who wouldn't have interest, don't have cap space, or both.
The list of teams that
1. Have the cap space
2. Have the roster need (suspend your disbelief long enough to acknowledge teams and GMs value Trouba more than fans) and
3. The Rangers would feel ok trading him there
10 teams:
Anaheim
San Jose
Seattle
Chicago
Nashville
Utah
Buffalo
Detroit
Columbus?
Dallas? (don't know where they go from here but they need RD)
I think there is a hockey trade to be made with any of those teams. he can't block all of them.
Fair. Im not against it.
