The only rational explanation for this is that the Rangers were bidding with another team, and needed to use the NTC as leverage over the mystery team. I am guessing this is a limited no trade clause, much like those given to Wade Redden, Michal Rozsival, and Marian Gaborik, in which he will give the Rangers a list of teams that he will/will not accept a trade to.
I don’t like NTCs, especially for players that I am already skeptical about, but it is what it is. No use crying over spilled milk.
The NMCs/NTCs page has been updated to reflect this.
