I don't see us as having massive potential really. If we get in the PL big crowds don't count for much, especially as we can't charge as much for tickets as the southern teams. The likes of West Ham for example get bigger gates and charge twice as much for a ticket. I don't doubt their hospitality will be much more lucrative too. The last time we were up there we were one of the lowest earners. I'm sure the commercial side could be improved upon and if we weren't so dull to watch, we might get a bit more TV money, but even so if we can't even compete with West Ham financially, how high can we go realistically ?
An investor could buy any club in the Championship and do the same but a year quicker.
