A lot of it depends on who's sent down. As it is, assuming Hodgson and Ebbett are up with Vancouver for now, the top line would probably be Mancari - Schroeder - Haydar, which is sort of weird since they all shoot right, like Anaheim's top line.
However if Hodgson does get sent down at some point, he'd probably be the No. 1 centre, shifting Schroeder down to line 2.
But if Ebbett gets sent down as well... then there's a hell of a lot of forward depth on the Wolves assuming no injuries. But in that case I see one of Schroeder or Ebbett being moved to the wing - depending on whether you want Schroeder to rip it up at centre this season (my preference) or if you want him to transition to the wing as early as possible.
