This can be self-fulfilling.
In an organization beyond a certain size, there will be more almost-adequate-fits than there are leadership positions. This could be about like a recognized baseline which seems like it really needs to be scrutinized closely to see exactly who might be slightly above or below the line.
Or in a small company where there is not any almost-fit whatsoever, imagination can result in an ideal that is equally recognizable, but also might not be fully attainable.
Either way it could be OK but not exactly the best-fit.
If good fortune smiles and the rare more-than-adequate-fit appears anywhere on the horizon though, it's so unfamiliar they fly right over the radar.
