Quoting: leafs101
a lot of GMs value the cup-winning big veteran defensive defenceman, someone would take him. He's a year removed from being our best defenceman (he was in 2020-21 season no doubt), and just had some injury issues this year. A team with minimal cap obligations over the next two years would take a chance on that, no question.
Well, you may be right but trades aren't done in isolation, what's available on the market affects choices and also price.
PIT is forced to trade either Matheson or Pettersson and both of those are more desirable than Muzzin due to age, performance, and resale value.
WPG are trying to both shed cap and make room for youngster and will trade Schmidt. He's also younger and more valuable.
VGK is in deep cap trouble and will trade Martinez, comparable to Muzzin.
The asking price for the above players is lower than what you're asking for here.
Then there's Scandella that will require picks going with him to be dealt.
It's a market well stocked with LD this summer and buyers are spoiled for choice, you may have to lower your price to get someone to bite.
