This big club stuff is a bit dated for me now given it clings on to our starting years when football wasn't anything like it is today. Even the early years were different to post WW2 when more teams were involved given some teams appeared later in history, Leeds being 1920s. I've had a look at the seasons and this is what it looks like overlapping the season positions with us in red and Leeds in black. Even Pre war you can see their climb into Div 1 and we lower mid table but the war put an end to that
This is post WW2 and the last 79 seasons so living memory for just about everyone. Without telling anyone who is who, which club do you think they'd consider to be the better of the 2? They've averaged 8.5th position in 40 top flight seasons, we've been 15th in 41 seasons. I'm not sure where you got the "made the numbers up in the top flight" for them as that applies to us even more. Overall in the 79 seasons, they've been 20th since WW2 and we've been 23rd.
Your last part about "fair chunk of them" watching them struggle could apply to all our fans who've started going from 2012 onwards given our struggles in the PL until we finally got relegated. In fact our last 24 years haven't been 'big' club performances and even less going back to 1985 which is 40 years ago. Don't get me wrong as I'm not saying we aren't a big club, just that we shouldn't really use the very start of our history as a stick to beat others in the way some do.
Just how long do we cling onto our more successful past from well over 70 years ago when football has changed so much over time? We could do in the 70s/80s etc but we've done little since the 50s and the longer it goes on the weaker it gets surely?
At the end of the day, football is fucked now as it's all about who has bigger revenues, the richest owners, location, richest fans, biggest global fan base, can 'cheat' the system finding loopholes etc. Long gone are the days of big crowds meaning a big club or players staying at clubs for any length of time as it's so easy these days for them to uproot and move on. Years ago players stayed longer at clubs as not all could be tempted away like today with multi million £ contracts so building a team now isn't as easy to do as the best players will be poached.
These days for us when it comes to 'big' clubs, it's more like 2 old blokes arguing over a comb when we compare ourselves to other clubs as it's very unlikely it will be like the glory days again when we had a full head of hair and plenty of money in our pockets
