AZ can use Halak and then expose him to Vegas.
WPG - as noted, their G is not very good.
ANA - Bernier is not a solution to backup Gibson - debatable whether Gibson is the answer too, however, Halak gives them a vet while in 'win now mode' [albeit, I think ANA trades Perry in 2017 to NYI]
EDM - Monster is cheap, but Talbot over a full season w/condensed schedule? Would be wise for Halak to offset Talbot and provide protection against injury. With all the good vibes in EDM, smart move re 'we mean business in being competitve'
PS - remember, McPhee was the goalie that acquired Halak in WAS. His successor traded him to NYI that summer after WAS did not make the playoffs.
