What I was getting at is that it is uncommon for a team to carry three goalies long term, not that they wouldn't be compliant with the 23 player roster limit.
I would be surprised if they traded Raanta or Kuemper, and I would be surprised if they carried three goalies long term. This seems like a quick fix with Raanta out. If they get lucky and another team has an injured goalie when Arizona is needing to move on from Comrie, they might be able to get a pick for him. Otherwise, he probably ends up back on waivers eventually.
One odd possibility is that they're merely "borrowing" him from the Jets?
I can't find the article anymore, but exactly 20 years ago the Canucks had started 99-00 with a bunch of injuries in goal and were at the very bottom of the claim order. The Red Wings were high on Legace, but needed him to pass waivers. Burke and Holland worked out something where the Canucks would claim Legace so he could back up Weekes for a few days, then they'd re-waive him and Detroit would claim him and thus be able to send him directly to the AHL. The whole thing went through exactly that way.
I guess that's a possibility for Comrie, but it seems a little off since the Coyotes could just keep another goalie they already own up to back up Kuemper and not have to pay the waiver fee and another salary.
My guess is something is going on with Hill where they'll need another AHL goalie and they're pretty certain Comrie will clear? Or maybe they knew other teams were interested but wanted to try to get him for nothing on waivers instead of trading something to the Jets, and now Chayka thinks he can get something for him from one of those teams?
Another odd twist to this whole thing is Comrie's contract. It's two-way this season and one-way next year. I would think if they were looking for someone to sit on the bench for a few games while Raanta is banged up, wouldn't they go for someone with less future investment like say Gillies/Coreau/Gibson?
