The reality is that an AHL team is never in full control of its roster, the parent club manages it to (1) develop prospects and (2) provide depth in case of injuries.
Further, as much as the Rocket had some good prospects in its lineup this year, the most successful AHL teams tend to be stronger on veteran players and lighter in promising teenagers.
So, I doubt that the Habs’ management team had any expectations of a long Rocket playoff run this year.
