There is no reason to clog up your goalie depth. You cross that bridge when you get there.
Most teams have 4 contracted NHL goalies. We even had 5 most of last year, including Price, with McNiven and then Hammond in place at times. Once Hammond was traded at the TDL, and Price was not available, Primeau was the only option around.
This can't happen for a whole season.
By the way, I believe the Habs do not see Poulin as a possible solutin even as a sub, or they would have signed him to an NHL 2-way deal.
Can't see anyone claiming him to start the season with a 2 year contract. I don't really care about a goalie better than him, I only care about Primeau not having to be called-up next season.
I agree that Primeau should not be an NHL benchwarmer for more than a game a month.
The solution is not to risk losing Montembeault (in which case Primeau becomes our #2!!!).
The solution is to find a new Hammond or other AHL-level goalie better than Poulin, hopefully who cleared waivers already.
