I am convinced that agents/teams leak these things to drive up the price. Its why the habs are always linked to every UFA.
As far as Brassard goes, he wouldn't be a horrible consolation prize. Could probably be a decent 3C on this team, maybe a lower end 2nd C. Would help the tank and at his contract would take it over a guy like Bozak. He only has 1 more year and could probably be flipped at the deadline for a 2nd round or 3rd rounder.
If habs added ROR, ROR/Danault/Brassard/JDLR is decent C depth much better than what he had last year.
Depends on the price.
