Ok your post makes no sense but I’ll do my best.Melbourne didn’t play finals in both ‘19 and were still struggling in ‘20 because they made it to the 2nd week of finals in ‘18?
Tigs dropped out in ‘16 because they played one week of finals in ‘15? How do you explain the 3 flags and a prelim from 17-20 then?
Weird examples, but you might be happy with one good year followed by one bad year, I’d suggest you’d be in the minority
I’d be happy with Richmond’s dynasty, and Melbourne came back from two average seasons to win a flag.
Geelong on the other hand, a model of consistency often challenging have made a grand total of one losing grand final since their last flag. Sydney are now a decade without a flag. Both have dropped out of finals. Both are back in contention.
Most teams that win flags have a few disappointments, often including dropping out of the 8, on the way. So you don’t throw the baby out with the bath water off the back of one season.
