Interesting that the Hab's would trade for a goaltender when they have Dustin Tokarski sitting in St.John's waiting to be called up. I hope I'm wrong but, my guess is that Scrivens is being brought in as insurance for when they have to announce Carey Price is done for the season with his second "lower body injury" in the last 2 years.
EG. Stage Two of the NHL-NHLPA joint Substance Abuse and Behavioural Health Program.
I know you aren't going to get much for Scrivens when he's playing in the minors, but at least get a draft pick so you can maybe draft one next year.
