That is the good side; there is a lower quality batch. But, sometimes, lower quality teams (especially, if they have been winners of competition(s) the previous season) are put in the higher quality batches, and this where you are 'forced' to up the quality of your team if you want to win the competitions, and when you made such an improvement, the next season you are likely to be put with even better teams. It seems that it is one of the way the business part of this game functions.
