Remember: Billionaire Bill said he would like to win the Stanley Cup as soon as possible. He backtracked on his ambitious viewpoint after GM George McPhee squashed the idea in an attempt at managing expectations, something all GMs who wish to keep their jobs have done for time immemorial.
I doubt whether McPhee will run out and trade for short-term UFA rentals and push the team to the cap ceiling like some GMs do to try and win in the short term. But he may opt to re-sign a UFA or two he had initially thought about trading at the deadline. For example, while the team's top two scorers Neal and Perron are about to become thirtysomething and ought to get decent offers at the deadline that McPhee would accept, it might not be worth trading Sbisa for a mere 4th round pick given how valuable he has proven to be to this team. Of course, he's a dman and with the glut it makes sense to move him, but maybe now he might not for next to nothing. Interestingly, Engelland, the 35-year-old Vegas native, has played so well he might be worth re-signing to a 1- or 2-year deal at a hometown discount if Deryk walked into his office and said he would accept a $1 million per year deal if there was a NTC. 27-year-old Marchessault is an intriguing UFA given his age and the fact that he leads the team in shots taken, and has 9 points in 10 games played. But, at the end of the day, he is only 6th in ice time and 5th in scoring among Vegas forwards, so the wheels of the playoff bus ought not to fall off with his absence.
Of the seven UFAs this season, I pray the team keeps Perron and fear Sbisa might be irreplaceable for a Vegas squad that wants to make the playoffs and make some noise once there! I can't imagine other teams not making substantial offers for Neal (5th in Vegas forward ice time but tops in scoring) and so keeping him is an unrealistic wish and really he has the most value to a team desperate in the short-term, like one led by one of the GMs whose job is in jeopardy if they don't have playoff success, which is not our team's situation.
The upshot is: Trading Neal or Marchessault might not derail the team whereas moving Sbisa or Perron likely would.
