Also, I would like to add. Think of it as 2 levels

1. Those teams and players who ran the table as being undefeated for a season
or a career.


2. And those who were and are undefeated in championships. They
never lost a championship that they played in, and it is more in relation
to star players or players who are/were number 1 or 2 options. Not
some bench player or short usage role player. And there must be 3 or more
championship appearances in a single era.
