According to Elliotte Friedman on Saturday's Hockey Night in Canada, Vancouver was willing to take Zaitsev in exchange for their own struggling defenceman,
Tyler Myers. Like Zaitsev, Myers has one more season after this one left on his current deal. His carries a cap hit of $6.5 million. Unfortunately for Ottawa, Vancouver was on Zaitsev's 10-team no-trade list that he submits every July 1st. He can be asked to waive. It's likely Vancouver did that and Zaitsev still said no.
