This offseason will be an interesting one.
Right now at the NHL Level the Flyers have:
Elliott signed for next season
Neuvirth signed for next season
Mrazek RFA this offseason
At the AHL Level the Flyers have:
Lyon RFA this offseason
Stolarz RFA this offseason
Tokarski UFA this offseason
Prospects the Flyers have:
Hart coming up next season
Sandstrom signed in the SHL for next season (Though there could be NHL language in the deal)
Safe bet Tokarksi is gone in the offseason, there is no room at the inn. I think it is safe to say at this point that Neuvi is also going to be on the way out this offseason.
The Flyers #1 goalie comes down to how well Mrazek does, and how well Elliott does upon his return from injury.
My current speculation is Elliott and Lyon on the Flyers, Hart and Stolie on the Phantoms for next season. If either Mrazek or Neuvi stays, they bump Lyon to the Phantoms, and Stolie to Reading.
