Megalabowl playoff inquiry

Forgive me if this feels repetitive for some of you.

But can you explain to me how the playoffs work in the Megalabowl?

I know about the percentages advancing, but how do you see other leagues and learn if you are in the top part advancing?

Secondly, can you continue to add and drop whoever is available in your specific league or do the roster construction rules change?

Thank you!

Last year we got a link to the tracking spreadsheet Ray used to inform of us of who was moving on in the playoffs.

You roster is locked once the playoffs start. You can’t add anyone after week 11.
