Quoting: Burnout
Montreal management was pretty clear that they're only trading Petry because his family wants to be in the US and they're only going to trade him in a deal that makes sense for Montreal. Sure, Habs fans make ridiculous proposals, but this is well beyond all but the worst of those.

Fans of all stripes have ridiculous expectations, but Habs fans have spent most of this season having their proposals for Lehkonen, Kulak and Chiarot called ridiculous only for them to generally be correct in terms of value.
The thing with all these trades sending him to Detroit for assets is that not one single one of those people doing them have even bothered to look at the Detroit roster or spent even one second thinking about how Petry would fit into Detroit's needs.
Detroit is set on RD for the future, with players 24, 23, and 20 years old. Why would we want to displace one of our young and upcoming players with a 34 year old, utterly overpaid, player that's on a declining slope? Not to mention that he has a contract structured in such a way that he's impervious to being bought out.
Detroit severly lacks talent on LD but we have loads of really exciting prospects. We really need to invest in at least one and probably two really solid defenders to play the left side and that will force us to go with four defenders on the left and three on the right which means that we don't even have room for Petry as a #7 defender. Petry would have to be waived and sent to Grand Rapids if we acquired him.
All that information can be gleaned by looking at the Detroit roster on this site for a mere minute or two. Thinking that Detroit would be a good trading partner for Petry really is delusional. Anyone doing the bare minimum of due diligence will understand that Detroit isn't going to view Petry as anything other than an absolutely massive cap dump and that Detroit will be demanding to be handsomely compensated if they should take him on to the tune of, at least, one 1st round draft pick for each of the remaining years of his contract. That is not a valuation of Petry, it's a valuation of how well Petry fits into the needs Detroit have.
A trade has to fit
BOTH teams' needs or it will never be made. Proposing such trades that
blatantly break that rule is, frankly, IMHO stupid.
