Because this: https://www.capfriendly.com/armchair-gm/team/915559

nmc, ntc. why waive it???? he wants to play hockey. he left the sharks to play in toronto. and he wants to retire here.

Because he is coming right back, never plays in ARZ - please read the linked team details.

there is no cap benefit by buying out a 35 plus player. read the FAQ link i sent you

I know that, but I don't think you're following how this works. The full cap from the buyout stays on ARZ who can absorb it, not Toronto. Read through the comments and you might get a better idea.

but why does a market like arizona whom takes money from the league to sustain itself, make a move like this, unless ur giving them valuable assets back.

Rumor is that the league was not thrilled about the Orpik buyout/subsequent lack of UFA offers landing him back in Washington, and has discouraged teams from planning that sort of thing on purpose.

Even if planning out such a sequence were allowed, the above says the Coyotes are paying over 6M in the first year of the buyout, just for a 2nd round pick.

The Avalanche got their goalie of the future (Grubauerwas top ten in the NHL last year in save percentage and gaa among guys with over thirty starts, I believe?) and Orpik for a 2nd. They bought Orpik out for a total of 3.5M over two years. Usually the buyout cost is lower than cap hit. Apparently on the last year of Marleau's contract, it's greater, because he was so old when he signed it, so this probably doesn't work for Arizona.

So the Leafs deal Marleau to the Yotes, Whom intern buy him out. So they can resign him cheaper. Yeah that's not aloud per the CBA.
