No need to even read it, At the time of the trade the NHL either allows the trade to go through or they do not.
This after the fact nonsense is just click bait.
I don’t have any opinions on the validity of this article.
However the league can and has explicitly reserved the right to cancel contracts it has previously approved. In the case of Hossa, Luongo and probably others the league approved their contracts, but explicitly notified the respective teams that while the league had approved the contracts the league considered them to be possible cap circumvention and reserved the right to void the contracts in the future, with potential punishment for the teams.
The most interesting question to me is whether the NHL has officially notified Toronto that they consider the Tanev contract a potential circumvention? Or has the NHL not done such and this just speculation from the media?
