True, but Tennyson isn't signed for 17/18 so he won't count as the 1D with 40 games and signed for 17/18 (unless they extend him). Murphy (as an RFA, assuming he's signed for more than 1 year or counts because he's an RFA) is the only one currently on the roster other than Faulk that can fall into the category. I guess if Carrick plays 40 games, he falls into that category as well.
I guess I wasn't very clear. My assumption is that they will get the extensions and, frankly, be happy for the opportunity. I think the gnashing of teeth around whether an unimpressive prospect or a marginaly NHLer getting offered a contract even if it means possibly getting picked up by an expansion team, seems a bit unrealistic. Both Murphy and Tennyson would jump at the opportunity, IMO.
I'm not sweating it either as it's a long way to the start of the season and, as I said, I'm 100% sure RF will solve this one way or another. It may be with another move, it may be playing Murphy or extending another guy, it may be playing Carrick 40 games, etc.... My only point was that I don't see them trading Murphy WITHOUT some other move occurring either before or shortly after.
