I disagree that Georgiev is the only goalie that can make this team a contender. Goalie is the one position, where a player might go on a spectacular SC run on an otherwise mediocre NHL career.
That said, they will keep Georgiev around because they are hoping for him to get mentally fixed and I don't disagree with that. It doesn't make sense wasting assets to get rid of him, you can't get a surefire replacement on the market anyway, so might as well keep him around. As the #3 at this point, until Annunen or Kähkönen give a reason for the coaching staff to give Georgiev another shot.
