I agree, and I suspect that the management probably appreciate this too. They must have statistics on the age profile of supporters, and no doubt would like to ensure that potential adult supporters don't drop off during their teenage/student years when money is more of an issue. If people are watching on TV why not watch a top team rather than your local side? It's visits to a live game that seal loyalties.
It would be interesting to know if there are any other factors in the club's number crunching. Would a season or two in Europe make a difference, promising the extra capacity if the ground were to be used for a tournament, FFP shenanigans on the balance sheet? It would, after all, be a capital outlay with rather longer term implications than a new mid-fielder.
So, it's not as clear-cut as some make out. After a reasonable start it will be interesting to see if the crowds pick up. I'm glad I've got a season ticket as it could end up a bit of a pain to get tickets for individual matches. I've done it in the past, but it wouldn't take much less commitment to take the attitude, 'blow it, I'll watch something down the pub'.
