Probably as stated below, it's not very convincible that multiple rookies get to beat down all seniors, even though it's true that the main characters (rookies) would have more spotlights in the story..

Still, chances are that S4 has to be changed again in the third year, so having all rookies win now is not a very farsighted plan.
