I think it’s a mix od culture, attitude and coach and energy he/she brings to the team.
Russians are generally very cold and have diva attitude on court with occasional emotions when they take big rally.. while Japanese for example are all very calm and respectful with similar smiley face regardless if they win or loose.
There is also some individual attitude of each player although they may act in similar way. For example I like seeing Cansu scream after a long rally (I know many people hate her overreaction ) but I hate Ebrar and Zehra attitude when they score, I’m not getting same energy out of them.
I miss some fire in Serbian NT after Veljkovic left, most of the girls now are just “good job well done yeah let’s focus on next point”.. I get the vibe but I liked a bit of attitude Veljkovic had and what it did for the team. Now it doesn’t reflect our culture and all bit it’s more of a coach (Terzic) effect imo.. Lazovic and Uzelac have some fire tbh and I like the energy whenever they were on field.
Not sure about Uzelac but Lazovic definitly has a very positive energy and I like to see her smiling face, having fun with the game. Hope she keeps going on with GS.
