Their personalities could not be any more different -- Colby Armstrong is so amiable, Michel Therrien so often gruff -- but their reunion likely couldn't have been more predictable.

When Toronto bought out Armstrong's contract last summer, less than a month after Montreal hired Therrien as coach, it seemed preordained that they would end up together again, unless new Canadiens general manager Marc Bergevin objected.

Which he didn't, so Armstrong -- who had played for Therrien in Wilkes-Barre and with the Penguins -- signed with the Canadiens the first day he was eligible to do so.

"I'm obviously comfortable with Michel," Armstrong said before Montreal's game against the Penguins Saturday night at the Bell Centre. "I've had him for a long time and know what he expects."
