When the new stadium opened I decided to dabble a little bit into the ticket resale market for the first time. In addition to my season tickets, a buddy and I bought single game tickets to some of the games I thought would be easy to sell and yield the highest margins.
If I recall correctly, reselling tickets to 4 games alone (Bears MNF, Cowboys, Broncos, 9ers) produced enough profit to cover the cost of all the single game tickets we bout that year and a little over half of our season ticket cost. That was even with taking hits on a couple of games.
So while I didn't sell my own tickets and attended every game, I can definitely see why folks and specifically Cardinals fans would engage in an enterprise like the resale market. Personally I decided it wasn't worth the time and effort after that first year and I haven't done it since, but for those that have the time and effort to dedicate it can be very profitable.
So with all that said, if BA is directing his comments to fans that are selling their own seats, then fine, feel free to call out their fanhood. But I have the feeling his comments and ire are misdirected.
