I don't remember hearing about health problems, but he did leave the team due to personal reasons right before the playoffs started.
I heard the same as AS, it came out that he was "sent home" then it came out that it was either health or personal reasons and would be rejoining the team shortly. I believe he was gone for no more than a couple weeks.
However back to what to do with Schneider, the other option if the WHL is unlikely would be to loan him to another ECHL club. As we saw with ADK, teams will loan out goalie slots to 2 different NHL clubs. Also we may not have ADK as our affiliate in the ECHL next season as the Flames sold the team.
Another option with the goalies is we keep both Rittich and Gillies and one of them becomes the backup next year.
Calgary: Elliott & Gillies
Stockton: Rittich, McDonald/Parsons
AHL Loan: McCollum
ECHL: McDonald/Parsons & Schneider (2 different clubs)
But I do suspect Rittich or McDonald ends up with the Vegas organization as they will not be able to take any waiver exempt goalies in the expansion draft and our goalie pool is as deep as any.
