just roughly what it's been most of the year when the line up is healthy
Check the GDTs. On the first page, there should be a post from the Merc's Pollak WRT recent practice reports. He usually lists 'em there. Or head to the end of the GDTs and look for the "Sharks recap" as they often summarize it there.
That looks like some Stanely Cup winners to me. I think Mitchell would be on the 3rd line with Goc on the 4th. Where does Claude fit in?
Claude fits in with this playoff forward lineup:
Lemieux-Goc-Roenick (or Goc-Roenick-Lemieux, but Goc takes draws since he 6th in all of the NHL in faceoff winning %).
There's your playoff lineup. Now in a series against the Ducks you might consider benching someone (not "6th in the NHL in faceoffs and Pahlsson style defensive forward playing" Goc) for Shelley, but otherwise the forward lineup above is where it's at.
