Akimi Barada was just an ordinary man. He wasn't an excellent head coach like Kawaki or even Akira from Tsunemori High. Hell, he didn't even meet the requirement to be a head coach. His former occupation before the disaster stroke was just a PE teacher, after all. The only reason why he could sit here as Fukushima Phoenix's head coach was because one of the team's new investors was an old friend and he was recommended to fill the position until the more capable person appeared to handle the job.
So, yeah, on the paper, Akimi Barada was not a qualified head coach.
