I'm not sure whether that is the case with Mrazek right now. Maybe they really want him to finally play 60+ games for the Griffins, or they think there's a couple of things he has left to work on? I don't know, but I would have thought bringing him up this season would have made more sense too, unless the Wings want more bargaining power when he's an RFA at the end of the year
They want him to play more, and I know I would like to see that as well. Bringing Mrazek up wouldn't change the starting goalie this year. If they chose not to sign Gus, then the savings wouldn't be very much because Mrazek would get more as a result of being called up. Now, if Detroit could save $2 million or more by promoting Mrazek, then I would be ok with it. That isn't the case though.
