Hagel was sold for a significant return -- (while Hughes held onto Anderson)
Hagel was 23 years old getting paid 1.5 million. Trying to contrast this trade (in what appears to be a negative way) with the Habs keeping an older player on a longer term, higher cap hit contract is disingenuous.
As for the rest of the trades (Debrincat, Kubalik, Dach), they all fit with the mindset of having to tank. The hawks didn't just dump Dach. They dumped all their productive youth for a chance at Bedard.
To suggest that Dach was some sort outlier due to injuries is just peddling in conspiracies so you can fulfill a narrative that you are smarter than Hughes and Co.
