This feels distinctly like, "quick, blame the old GM for being dumb" sort of spin, distraction tactics.
It's distorting a previous situation through the lens of today though. If you were offered Romanov and a pick for Boeser and a bad contract today, you'd be a moron not to take it and run away gleefully.
But at the time, Boeser was very much looked at as "part of the core", Romanov was a complete unknown and questionmark to even come over to North America (for a team in Vancouver that was having trouble retaining Russian talent at the time). He was a good prospect, but hadn't played an NHL game yet. Boeser was also on a very good contract at the time.
If the Habs are still genuinely interested in Boeser...despite having a completely different regime for BOTH teams involved here...then yeah, let's heat it up and get a deal done. But it feels more like someone spurred Dhaliwal to fire up some "Benning sucks" fervor to distract from the fact this new regime are still kinda waffling and floundering and have a complete PR mess on their hands with the Horvat situation.
