The NHL could be getting a new team or two. Of course, when a team joins a league, they can't start purely from scratch - they need to acquire players, and the main way they're going to do that is via an expansion draft.
GM's told expansion decision expected before June draft. If expand by 1 team, each team loses 1 player...if two teams, 2 players.

Naturally, though, the existing teams will be able to protect some of their players; top players aren't going anywhere, if teams are smart about it.
