Collingwood haven't had any genuine downs in the Eddie eraRichmond would have been the next on the list obviously. Collingwood I think are on the fringe. Some big highs but some fairly bad downs at times too. I'd group them with an Adelaide.
04 and 05 struggled but bounced right back
Missed finals 4 yrs in a row with Bucks but were never bottom 4 or anything.
And in that time they've been right at the cusp of a premiership in 3 diff eras- 02 03, 10 11 and 18 19.
That's something I've noticed- power clubs like Coll, WC are rarely down for long. Carlton the one exception. Even Ess, yes they have been unsuccessful but they've rarely been right down the bottom.
Clubs like Saints, Melb and Dogs have found themselves struggling and its taken them 5, 6, 7 years to get back into finals. And they really bottom out. North hasn't made it 4 straight years and won't be back anytime soon.
