Which 9 would you consider to be locks with both Datsyuk and Franzen out? Zetterberg, Richards, Nyquist, Tatar, Sheahan, Abdelkader and Helm make 7. I don't see 2 other players who are guaranteed a spot in the top 9. Obviously we'd like for Jurco and Pulkkinen to win spots, but their roles are still undefined.
For the record, I don't think either Mantha or Athanasiou are ready for the NHL (I suspect Nosek is ahead of both in terms getting a call-up with the Wings). I see Larkin as the only prospect with a legitimate shot at getting into the lineup on opening night; he's simply a cut above the rest.
