The ones who don't have over confidence are veterans who have been using their powers for long and fought someone who defeated them. Crocodile was defeated by WB. Admirals obviously have someone over them who can defeat them(Sengoku) or they may have fought with their uppers like garp-san teaches coby and the whoever.
