Japanese Situation Leading Into Midway

if anything, the japanese seemed over-confident. that's how i saw their plan. the first and second air groups were the best they had, compared with the fifth who fought at coral sea, they were a league apart. so if a bunch of nobody's can hold their own against the best american pilots at coral sea, what more for their elite groups?
