Nah, they were drafted just fine. Thought Boland or Carson MacKenzie could have been picked up, but it's not necessarily wrong for teams to just prefer other players over them either.
For NL, I do think it's underscouted a little bit most years (doesn't mean that more players should get drafted in the end).
That said, this year there was the Q Cup in Dieppe, the Monctonian, the Icejam, the Canada Games where there are 4 maritimes teams and then the QMJHL Cup at the end too...
If anything, the maritimes players were probably more heavily scouted than ever this year, so it's certainly not a flaw of not seeing these guys enough or not having scouts.
Even I, from Quebec, was able to see most Maritime players at least 10 times each this season...
