I do not agree with you because what you said may happen now and indeed certainly happens, but we do not know. Even now a team may decide to play the game of life (mots) against an opponent just to promote other team more sympathetic. I do not understand what is the difference between the current situation and what might happen with my suggestion.
I start from a different point of view: BB is a game where everyone wants to win more games to be the best, there is rivalry between all managers, and the friendship is only to write to the same forum or send private messages.
I think that the not introduction of a change for its possible negative consequences is a reasoning too superficial.
Even the increase of salary for inside skills for PG and SG next year is a change that will bring serious damnage to all managers who until now have trained the inside skills in outside players.
Even this innovation will lead to negative consequences, much of my suggestion.
