Yeah, I don't disagree (although Notts County have had a fair amount of success).
I still think they are underperforming though. I often consider big clubs in terms of potential. Bradford is a big city etc, anyone who makes a big success of a Bristol club would have a big club on their hands, Carlisle could serve great swathes of the north etc...
But yeah, not comparable to clubs like Sunderland and Sheffield Wednesday
