I'm as high on Sproul as any prospect in our system but he still has a long way to go before playing for the Wings.
He struggles with Defence in the OHL, even jumping to the AHL i expect him to make ample mistakes leading to a lot of -'s.
I do think his offence is unlike any defenceman we have at any level of our system though, he will quarterback the PP and put up pts even if he gives up a few going the other way. I think he'll be much improved next year if he's paired with a strong defensive guy like Ouellet.
Next year is going to be a big one for Grand Rapids, although they will probably be hurt up front losing Nyquist, Tatar and Andersson (Hopefully)
