The perception is the Canadiens’ roster has been carved in stone over the last year. Nothing can be further from the truth.

When the Canadiens open their 2010-2011 season on Thursday, nine players will be on their roster who were not with the team on opening night last year; a 39 percent turnover.

The Canadiens will declare their roster at 3.00pm tomorrow, set probably at 22 players.

Today the Canadiens asked waivers on defenseman Alex Henry and goaltender Curtis Sanford. Tomorrow, because they don’t require waivers, defenseman Yannick Weber and forwards Ben Maxwell and Ryan White will also be sent down, leaving the Canadiens with 22 players including Roman Hamrlik and the suspended Michael Cammalleri, but not including Andrei Markov.

Gone from the team that opened the season in Toronto (Oct.1/09) are – Andrei Markov (injured that night and injured again), Glen Metropolit (UFA), Georges Laracque (Buyout), Paul Mara (UFA), Matt D’Agostini (trade), Max Pacioretty (reassigned-Hamilton), Guillaume Latendresse (trade), Greg Stewart (UFA) and Jaroslav Halak (trade).

Markov is still here, but the others have been replaced by Lars Eller (trade), Benoit Pouliot (trade), Mathieu Darche (from Hamilton), Jeff Halpern (UFA), Justin Boyd (trade), Tom Pyatt (from Hamilton), P.K. Subban (from Hamilton), Alexandre Picard (free agent) and Alex Auld (free agent).

And those who think the Canadiens haven’t made use of their farm system should note that Darche, Subban, and Pyatt are all callups from the Bulldogs.
