Alright, chikkychappy, you can have your words and I can have my words. I don't want to quarrel with anyone in this forum.
The worst buchou, I would say Rokkaku's captain. He is selected randomnly by his coach. He is never a good buchou to start off. He is too confident in his tennis that he always let others to score a lot from him in the starting and planning for a come back later. He should show a great leader's style by confirming his team's win first rather than just for his own joy or pride.
