So this year Glenelg debuted on the ladder in second spot after their win against West in round 2. I think every time they changed position on the ladder it was downwards, eventually finishing in sixth.
When else has a team only gone one way on the ladder?
I recall Woodville debuting in top spot after round one back in the '80s under Mal Blight, only to finish last. That year might be a candidate. Also in '95 Port would have debuted on the bottom after round 1, then didn't drop a game until about round 10, did they go down at any point in that year?
