They are not only destroying years of planning, based on competing under the rules that have been established. It is very difficult to compete in B3 without running at a loss, even more so now with the increase in the salaries of defensive monsters, who were the players that helped teams avoid having an entire starting five with exorbitant salaries. Therefore, you need cash reserves to cover those salaries and compete at that level.
But there will be another problem as well. Even today, high-salary players are being sold at bargain prices, and they can only really be maintained by teams with B3 ambitions or farm teams, which, in my opinion, are much more harmful than a team with a long-term project. As a result, these players will be worth even less in the future.
