I think Koledov broke out and really made a name for himself last year playing for Sochi, Loko still have plethora of great young Ds (Gavrikov, Rafikov, Lyubushkin) and realistically room for one of them, at best, they should really loan some people out again.
One name that came to my head instantly was Anatoli Golyshev. It seems like he will easily score 35 points this season.
Others include:
Albert Yarullin - a case can be made he broke out last year in Atlant and move back to Ak Bars will only hurt him
Nikita Tryamkin - he's a prized prospect but never really was impressive at KHL level, will have so much more opportunities this year with Lepisto, Viklund and Metlyuk leaving the team
Ivan Telegin - looked very good in the pre-season, can really play if he gets any kind of minutes on stacked CSKA roster
Artur Gavrus - this one is kinda obvious, it's only a question of time
Denis Guryanov - again Cpt. Obvious here, even though I doubt it's actually going to happen for him this season already
Alexei Bereglazov - he has some real offensive flair and he will get minutes this season
Somebody on Kuznya's roster - because it's how world works
Vyacheslav Leshchenko - because again, he has the talent and he had strong rookie season it would be only natural if he broke out in sophomore year
Vasili Demchenko - I realize he's only gonna be a backup and in that light he broke out last year already but he's a real KHL goalie in the making, might be a real competition for Francouz
Some older guys too, like Vincour or Brule can score in the right situation obviously and have been duds so far in the KHL.
