ok i just dont understand why u think thats the case with them
the kc manager doesn't make any roster, the rosters in kc are usually made like this : the coach, the players, the staff, and in this case i think (NOT SURE) that engh is making the roster by himself, trust the process
edit: theory: he OBVIOUSLY asks players if they WANT to play with X player or not, you cant put a player with someone he doesnt wanna play with
