Any stats on what the uplift actually is of winning a comp? Maybe 10-20% in the winning season? Seems to me if form drops off in the following year of winning a comp the fans soon do as well. Probably need sustained 3-4 years of good form and premierships to see any sustained fan growth. Be interesting to see how many Panthers can hold on to when the inevitable happens.
List of average crowds for every premier in the year they won the comp with the next 3 years in brackets. Any subsequent premiership in those 3 years is bolded

The exercise has to stop there due to COVID
So discounting the 2019 roosters, of the other 21 premiers listed, 14 of them did increase their crowds the following year but not drastically with an average increase of 1732 or 12.48%. That only takes in to account teams that did increase, so using the full data set including teams that decreased the average turnaround the year after winning a comp is 505 or 4.82%
In regards to the 3 year outlook after winning a comp, using the teams up until 2016 Sharks which have full data sets not impacted by COVID, of the 19 premiers in that time frame, 12 had a worse average in the 3rd year after winning a comp than the year they won it with an average drop off across the 19 teams including those that did increase of 1361 or 6.94%.
So yeah, at this stage I'm willing to say that the notion of Parra being some crowds powerhouse if only they could win a comp is BS and that crowd growth is more tied to being consistently competitive as opposed to actually winning the comp.
