No, I mean arguably our lowest point ever. Even in the 30s when we hit the bottom division we were pulling in 15-20,000 and never averaged under 10k- for some games we had 40k, plus we owned our own ground and had no history of top division football so it was more 'normal'. The only other season we were in the bottom division was 58/59 when we got 17k per game, and again we owned our own ground. That was generally felt to be our 'lowest ebb', however in 2017 we were down to crowds well under 10k, did not own a ground, the ongoing SISU stuff was happening, we went through god knows how many players, we'd bounced from Northampton to the Ricoh only for that to get sold to Wasps- and we were in a time when the financial disparity between divisions was higher than ever, it was as if the club lurched from one catastrophe to the next, and we never knew if the club would continue to exist, let alone climb back up the divisions.
There are only really two competitors for our lowest ever point since we joined the professional league- the 30s and that one season in the 1950s- but in both other occasions we had a ground, good support, and we did not have constant threats to our very existence, so I would say that when we hit rock bottom in 2017 that was the absolute lowest. It was only really Robins coming back and a day out at Wembley which gave any hope at all. There is no hard & fast answer, just opinion, but taking everything into account for me, 2017 was the lowest ever in terms of league, support, morale, stadium and the very future of the club.
