I can understand the theory that people who didn't get to see a game maybe less likely to be hooked and I'm sure the positives of promotion won't be as pronounced as they might have been with a bigger ground.... However, thousands of new fans did get to see them in league games, cups games away games, on telly, on MOTD, in their sticker albums and in there fantasy football teams.
There is a generation in this area now that have grown up as AFCB fans whether they got into DC or not. The proportion of under 21 year olds that support afcb over the other clubs is higher than its ever been as is the number if replica shirts and afcb merch you see around the town. Some may drift off to other things but a shitload will be afcb for the rest if their lives.
As much as it pains me to say it, Swindon have always got 1,000 - 2,000 more than we have through the gates. This is because they've had a purple patch that we'd never had. Well we now have had it and we'll never go back to 4,000 odd average gates. In fact I don't reckon we'll ever drop much below 7,000 averages again no matter what happens.
We probably won't sell out but we'll have thousands more fans than we would have done had all this not happened.
