The only time we had any real increase was the Armstrong season.
Even when we were doing well in League 2, we couldn't muster 15k for a league game. We couldn't even manage a good crowd for the play off first leg.
If we were to get back to the Ricoh the first game would be around 13k.
However, I do genuinely believe in the championship our crowds would regularly hit 20k. The away followings in that division are huge. The vast majority take over 1500 a week and there are about 10 clubs who could sell 5000 at the Ricoh. Plus, playing the likes of Leeds as well as local games against Brum and Forest would feel like cup finals compared to Forest Green and Fleetwood we have become used to.
