Geelong's 2020 team was about the 11th strongest team they've fielded since the turn of the century.And if Geelong had beaten Richmond in 2020 would it still be weak. It's sort of irrelevant if it is a weak era or not, you can only play the sides around, which makes the other including Geelong, weaker than Richmond.
So the answer would be yes, and Geelong supporters would be amongst the first to agree.
