    Probably better phrasing would be “Those who used to do, teach”. As in, teachers/coaches might be people who due to any number of circumstances can’t participate in doing the thing directly, but have experience in it.

      The saying itself is a pithy dig at teachers, it’s meant to demean their skill at what they’re teaching.

      It’s a witticism, not a measured statement of truth.
