It's pretty simple to understand. Tickets are easily available on the resale market. Season ticket holders can sell a game or three and make their seasons ticket price back. Stadium drinking is down so in stadium atmosphere is much improved for visiting fans. Back in the day, you had to get tickets direct from the Team, making it a challenge for out of town fans. Now with the internet, easy-peasy if you are willing to pay the going rates on the resale market. My buddy just told me he sold his Miami tickets for 500 each. Nice seats, 20 rows up from field at 50 yard line behind Bills bench. But 500 each, yikes!!
