Monster, Budaj and Fasth are all still available and could be signed for a cheap 1 year deal.
Calgary has Hiller, Ramo and Ortio all waiver eligible. They don't want to lose Ortio for nothing, so they'd deal him or Ramo pretty cheaply. There are probably a couple of other teams with similar situations I could find if I checked.
I would sign 1 of those vet ufa's. I'd Make Subban the starter in Providence with Smith his back-up. I'd have McIntyre get start in the ECHL where he can play every day.
If at some point in the season it became clear that Subban or McIntyre deserved a promotion, the you move the vet ufa or Smith.
If we do nothing then what we have is either
a)a career AHL goalie in Smith as our back up with either Subban and McIntyre splitting time (not good for either) OR Subban getting the bulk of the starts and Zane in the ECHL anyway.
or
b) Subban/Zane sitting on the bench in the NHL behind Rask
My way is the best for 1) winning this year and 2) giving our 2 best G prospects maximum playing time.
Again, make them EARN a promotion, don't hand them a job and then see if they fail and react then.
