Again, I would argue that one of the major weaknesses of this team is the lack of "winner mentality". Sabonis is still carrying the team on his back, but even he does not hold others accountable for their actions, as a true leader would do. Monk was the "hype man" from the bench but the Milwaukee game kinda broke him.
Sasha on the other hand has a lot of experience, played in finals (something taht Fox, Domas or Lyles or whoever have not yet experienced) and has dealt with the pressure of European basketball crowds, nothing compared to the kiss cams and T-Shirt throwing in the NBA.
He might be still adapting to life in USA, language, even culture and food and seem a bit disengaged, but I am sure that once the coaching staff recognizes him for his personal traits as an individual and leader, he will start getting more and more minutes.
I still believe that the Kings cannot fully understand what kind of asset they got in Vezenkov and it will be a pity if Brown keeps ignoring him and treating him like a rookie...
