I think this is the key. Let his play decide where he's going to be. Right now the #6 though about 8 spots are a toss up between Nurse, Oesterle, and Reinhart. Oesterle's a safe bet for the #7 due to waivers, but either Nurse or Reinhart could snag that last spot, assuming no new bodies are added.
Though I'd still like to start off by pencilling him in Bakersfield to begin with. This is the Oilers we're talking about, injuries happen and both Klefbom and Davidson have shown enough to be concerned on that front. Nurse'll get his shot soon enough(Same with Reinhart).
