I Have a Theory

You know how you can tell a good leader from a bad one?

A good leader brags about their team.

A bad leader brags about themselves.

And I think I know why that is.

The modesty of a good leader isn't feigned, it isn't a facade.

In my experience, someone who leads well, except in some extreme circumstances, generally doesn't feel like they're doing much of anything at all.

The modesty that comes from good leadership isn't due to politeness. It comes from the fact that "No, really, from my perspective I didn't contribute much at all. My team's just that awesome."
