The Avs can still get the #1 seed in the west. If they win out (with at least 3 regulation wins) and Vegas drops just a point in one of their remaining games, the Avs will have the best record in the conference.
Vegas has a home and home agains Seattle, so not out of the realm of possibility they loose one of those games.
If Winnipeg wins their next 2, they will have the last wildcard spot locked up before they play the Avs on Thursday. At that point the teams the Avs play in the last 2 games will have nothing to play for, as their positions would be locked in.
