Even if the Flames were completely kept in the dark, I don't think including 'mental health' in the Flames statement was appropriate.
There were indications back in November that the names were about to drop - and the only thing stopping them at that point was a Hockey Canada appeal.

The Flames may not have known with certainty that Dube would be charged, but they knew he was involved in the investigation.
To include mental health in the statement just reflects incredibly poor foresight and PR by the organization.
