Average Schmucks could rather easily afford pretty good seats. Dad and I often sat at the 35-40 yard lines for considerably less than an NFL game. The Jacksonville Bulls did very well with attendance. I remember the 85 game vs the Generals with Flutie and Herschel. There was about 75 K there that day.
Till the League shows SUSTAINED proof of quality and no fan gouging, I think people are going to be reluctant. Everyone is tapped out on being fleeced at every turn.
