I think as far as the forwards are concerned, probably. Though as it stands one of Josefson or Kalinin will have to play 3rd line C instead of 4th line wing, which isn't ideal. But almost every single forward they have is either a recent acquisition/signing (Josefson, Kalinin, Fiddler, DSP, Bennett, Hall), or probably not going anywhere (Henrique, Palmieri, Zajac, Cammalleri). Counting Boucher, Blandisi, and Zacha, that's 13 forwards already. Blandisi probably starts in the AHL and Zacha may or may not make the team, but I suspect he will. Not much room for any more forwards there, particularly considering there are a couple more guys in Albany that will warrant callups at some point.
They really need to add a solid 3rd line center, but someone get's kicked out of the lineup then. It's possible they could include Boucher's rights in some kind of a deal for a defenseman, then sign someone to center the third line.
As it stands, the only deal that makes any sense is if Shero can somehow cobble together a package for a top-4 D. Though after seeing what Larsson went for, I seriously doubt he can pull that off.
I'll be cautiously optimistic, but very concerned about the D if this is what we go into the season with.
