Do you think Hara is sidelining the Great Generals (minus Riboku) in this arc on purpose?

In the current arc three of the four participating Great Generals are currently sidelined. Yotanwa is injured and can't really do anything right now. Ousen and Shibashou are on stalling duty and neither of them seems to be doing anything either. The only Great General that is active is Riboku and I think that's on purpose.

I think that Hara wants to focus on the young generation right now and wants to give them major achievements in this arc, which is why the Great Generals are currently out of the picture. They should get more important roles later on in this arc though. What do you guys think?
