That's not how players and teams work.
They take the ice at the start of each game with the intent of winning the game. There's no manoeuvring or jockeying for position, except maybe when it comes to tanking for a number one draft pick.
There is no one in coaching or management advising the players on what they need to do to get this or that playoff position. No one is saying, "Lay back and lose this one, boys." You're suggesting that Vegas is not currently playing to their full potential because of the current standings, and that runs contrary to the mindset of every professional athlete who's worth a damn. I'm guessing you've never been one of them and you've never thrown your heart and soul into the game you love and competed to win each and every night.
In my opinion your opinion is a result of being offended at the Canucks' current success, and not any sensible theory.
