Well, 1 year in real life corresponds to 1 season in BB.
It's obvious that the goal is not to complicate the work of new teams. See it a higher level by awarding team which work deeply with their roster instead of buying and selling for a yes or a no. For example at the highest level, winning the B3 is almost only a question of money. Usually you save up and buy very expensive players to do kind of one-shot... it's a non sense.
Whatever, the goal is this idea to be seriously discussed and addressed by Marin and build an equilibrated solution to insert chemistry in the game the best way
