Well, in Esports a lot of it actually falls on the players.
Look at G2, shox gets what he wants (Carlos pls kick this idiot)
The Fnatic players wanted Xizt, also wanted to get rid of golden and lekr0
NiP want to keep GTR and F0rest (can also be for marketing purposes though)
Not all of the above players are bad, but they include some questionable roster moves at times (Especially Fnatic, wtf did they do with godsent it was terrible)
Lots of players blame coaches and use them as scapegoats for being shit. Look at the NBK and Shox drama before that G2 lineup ended and Shox's reign of retardation began (Vitality #1 French team).
At the end of the day, if two players don't get along, it can cause a roster move regardless of the org.
