There was no bigger piece of evidence that the Boston Bruins believe in creating competition at all positions, and at all times, than the club’s signing of free agent Dany Sabourin.

Although the Bruins would obviously love for prospect Tuukka Rask to blossom into an NHL-caliber goaltender this season, they covered themselves with the signing of the 29-year-old journeyman, who has shown the ability to succeed to at the NHL level even with scant playing time.

If Rask isn’t ready, Sabourin should be the perfect guy to give Tim Thomas a breather every other week or so. Sabourin, who started skating with his new teammates in Wilmington, Mass., this week said he’s excited to get going and work with Bruins goaltending coach Bob Essensa. The two spoke over the summer about their plans for this season.

Offseason tidbit: Sabourin skated three times a week with his goaltending guru Daniel Coutu in Val d’Or. He even went through drills with kids during a goaltending camp.

Position battle: Should Rask beat out Sabourin for the No. 2 job in Boston, Sabourin will battle rookie Matt Dalton and returning prospect Kevin Regan for playing in Providence (AHL).

Projection: It might not be the worst thing in the world for Rask to start the year with the P-Bruins and keep playing regularly. But if he has a camp like he did last fall, then he’s an NHL goalie and Sabourin would be relegated to the P-Bruins or a team that might claim him on waivers.
