The "problem" to answer your question right now is our management. They are maybe the most silent management group in the whole NHL and will NEVER say anything that they are not 487% sure about.
And they do there own staff, so there is quit a chance that he is not allowed to play in the NHL even if he is ready, because they say the guys out of the A deserve their chances (and we have lots of those guys in the A).
And the newest question mark right now is, they are testing him at playing center, so maybe they send him back because they want to make a center out of him and say to Halifax they should train him everything needed, which would just be logical.
That said, I expect him to be up, but nobody knows, so I would go for a veteran, more safer player and either hope you can still land Drouin at 8, or try to move up from 8 and land him then (if possible)
