It all depends on your opinion of the players. I do not believe that Martin or Clutterbuck are NHL level forwards over the course of an 82 game season plus playoffs. I do not believe that there are NHL-ready forwards at the AHL level that can be plugged in if there was an injury in the top 9. This may change with the development of some of their young forwards, but not yet.
The upside of this season compared to last is that there is potential to have 3 competent lines. Unfortunately, because of poor forward depth, we have a guy like Holmstrom on the first line.
As far as defense goes, I also agree about poor depth. Even Bolduc has not shown to be a competent 5/6 dman to this point.
