Keep in mind, if he plays in the AHL, we burn the first year of his rookie deal. However, if he plays in the AHL, he can be called up to the NHL at any point- so, if the brass think he's only half a season away, the AHL is the right spot. If he's a full season away, he should play it in Sweden so we don't burn a year of his rookie deal.
So yes, OHL is probably last on the list.
