To identify the NFL teams with the most expensive tickets, event ticket search engine SeatGeek provided 24/7 Wall St. with the current average secondary-market ticket prices for each team for the 2013 NFL season. 24/7 Wall St. reviewed team record and attendance data from ESPN. We also reviewed city cost of living data as of the first quarter of 2013 from the Council for Community and Economic Research. All ticket prices listed are secondary-market ticket averages, provided by SeatGeek. These are the NFL teams with the most expensive tickets.
So, they ignore face value and go off secondary market values, ignoring which tickets are available in those markets or how many people are actually paying the inflated prices... Just the prices, whatever that means. Those may in fact include or only be tickets that failed to resell, which would really be a measure of the resellers stupidity.
The data is something, but it is hard to tell what.
