Right now I'd treat Marty as a #2 or even as a spot starter depending on the rest of your goalies.
For example if I have Price and Pavelec on the same roster, Marty will be on the bench most nights. If on the other hand I have Rask and Mason or Niemi teamed with him, Marty will be in there much more often. And I may have jumped off a ledge by now as well, but that's beside the point.
All said and done I can see him as a #2 with a slim chance of regaining low end #1 status. It's just more realistic to see him as a #2 or spot starter.
