I can't stand Therrien, but even a stopped clock is right twice a day. Asked about Drouin, he commented that with him, "there's always something." Some injury, some issue, some problem - some excuse.
Same pattern with Armia. When everything goes just so, he can be tremendous. But when it doesn't go just so - when he gets a hang nail or whatever - whoops, he vanishes.
Maybe something transformative occurred this year. Anything is possible. But it would be folly to make longer-term decisions based on 6 months of aberrant performance. The plan has to be to trade him - whether now, or later, or at the deadline.
