In round 1, the lack of finishing moves for the Golden Generation will give a good chance to the teachers.
However, the teachers themselves lack range and with Sakura having her strikes and Temari having her fan which she can wield at a level to rival Lee in combat, close range is a loss for them.
Their best plan would rely on Kurenai providing support with kunai throws and bombs while Kurotsuchi uses Earth Style to destabilise the youth. Unfortunately, the illusions Kurenai uses are close ranged and we know not of any long range manual illusions she could try. Even if she had any, Temari could potentially blow the energy for them away (she could blow away sound) while Sakura breaks out of them.
Overall, Temari with her fan has the fastest and most ranged attacks while Sakura could blitz ajd destroy any earth with her Yin Seal. The youth win with more convenient attacks, although the combination of the teachers is stronger.
In round 2, the summons allow either girl to go alone. The slug can be summoned at 5% size to simply obliterate while the weasel blitzes everything. It's a mismatch.
