Spring in Fialta
A malign star kept him
I dunno, the series of events that led to all this happening is honestly pretty contrived and hard to realistically foresee. He's got 15 slots and if he had the other 6 Canadian teams plus the west coast teams on it, that's already 12 or 13 spots taken. I think it probably made sense to leave the Habs off the no trade list. With 15 slots you can't protect against every negative outcome and I think it was reasonable to expect there was an extremely low chance of Montreal reacquiring him, and that if they did it would be to flip in this way anyway.
He got traded away from a rebuilding Canadiens team to an aging but still competing Penguins team, the likelihood that the Penguins would go into summer 2023 trying to compete and specifically be targeting the reigning Norris winner at the same position as Letang & Petry, the Habs would find a fit in a three-way trade with the Sharks due to Mike Hoffman being untradeable, and that Petry going back to Montreal was the cap move that made a trade for a resurgent Erik Karlsson work is not something anyone could have reasonably projected or planned for.
Yeah but you can do this with a million scenarios and considering his state of mind when he actually did end up traded, it's not like the left on a bad note.
My point is more that Montreal shouldn't have to take a worst deal because he doesn't want to be there. If you're adamant on not wanting to be in Montreal, put them on your list or report. I personally would have preferred to play him as opposed to getting this return/using a retention spot but if Montreal actually likes the player they got back (which seems to be the case according to a reliable poster) then it is what it is.
In short, if Petry did try to game his NTC, I have zero sympathy for him and I wouldn't bend over to his will and I'm someone who's 1000% into the human side of things/understanding that players have concerns that go far beyond hockey. But that would be something I'd have to put my foot down on.
