They aren't doing a very good job of buying the title this season. I find it interesting as any other coach managing SKA would have been sacked and exiled long ago but not RomanSKA continues making a joke out of this league trading with its farm clubs (Randulic is coming from Sochi) and poaching other teams for players (Serbryakov).
The concept of building a team does not apply to them, they just want to buy the title.
Interestingly CSKA (Yurtaikin trade non-withstanding) is not trying to keep up improving the roster. Without fresh blood there may not be enough motivation there to fight for the title.
