First off, the answer to this question is very different in Spain and a smaller country in terms of how long it takes to reach division III and how strong the teams are that have made it there. We've stated many times that division III teams should be weaker than division II teams, etc. However, that's only half the battle - the second goal is that when a team promotes from III to II, they need to be given enough resources that they can stay in II and be competitive. What this means effectively is that teams at the top end cannot be allowed to save massive amounts of money - for a Division II team to stay in II, they need to be forced to spend almost all of their income (on some combination of players, staff, transfers, arenas, etc.) in order to be competitive. As long as this is true, then if a division II manager demotes to III they will have to sell off part of the team and will not simply dominate III. On the other hand, division III managers are competing in a zero-sum game; your comment reminds me of a bit of chess annotation I once saw where the commentator claimed "both sides stand worse". No, it's a zero-sum game! But if you're asking whether you can maintain a division II caliber team in division III? I hope not, because otherwise it's impossible to compete with a team that demotes.
This thing you comment it was happening since season 8. Teams arriving from II to my III was able to
keep the same roster and maybe the first season they dindt promote, but the next yes(and i was asking myself how the hell is posible they keep the same roster?(
Contract TV).
While the teams arriving from IV just the bests were able to compete(the level was close) and most of the teams they were demoting to IV again. And i was on the middle of the table that seasons(ive been) no promoting, but no demoting. I had to train young players and lot of primary skills to stay competitive, but now what?
TV contract was a big fail which helped in that direction you said, but now teams that always did the right things
we are going to get frustrated. Yes, for the first time after 8 seasons on the game im going to go frustrated with the game, managers who keep taking right decisions are penalised again, and specially on Spain where on medium divisions theres a close level.
We will have to sell to be competitive(if not bankrupt coming soon) and we cant keep training because if not salarys are going over us and if you dont train really hard on a close div. III you are demoting to div IV.
So now we are going back, its good the BB's admitt the mistakes,
but the new measures arrive late and they arrive on the wrong direction
PD: I was close to become supporter and i was thinking to be it, but im sorry im getting frustrated with the game and disappointed with the economy, i see i wont have a chance never, because on 2-3 seasons a new rule will come and i will get penalised again and again. And its the feeling we all have on Spain(specially medium divisions managers) we are really frustrated, even if we did de right things with a long strategy term.
