Winnipeg and Edmonton are the two teams most likely to appear on “no-trade lists” per this article and others:
Report: Oilers, Jets top no-trade lists - Article - TSN
This may have changed slightly as the fortunes of the jets have changed, although I believe it’s from the year we made the playoffs.
As such, it is a reasonable assumption that Winnipeg (and Edmonton) is a team on a specific no trade list until proven otherwise. As much as we love Winnipeg and many players come to love the city, it’s still cold and lacks the perceived sexiness for a young athlete that LA, New York, Tampa and even Florida and Phoenix have. There’s also an incredible spotlight shone on the players in this market, which not everyone may want. This is just a reality.
