in the land of the blind, the one-eyed man is king
Proverb meaning that someone of mediocre ability can stand out when surrounded by those even less capable. Literally 'a bat in a village without birds'.
In that company, he's treated like the top ace, but it's really a case of 'in the land of the blind, the one-eyed man is king'.
