The McDaniels' experiment opened up a LOT of season tickets over the last couple years, dropping the waiting list down to only five years or so, but at least temporarily that's changed. They claim about 98% renewal this year. If you figure there are about 24,000 season ticket accounts, that means at most about 500 people on the 23,000+ waiting list got tickets this year.
Assuming the team goes back to being an annual competitor, that's probably going to be the norm.
Also, for the first time in several years, all the club seats were sold. They were sold out within 24 hours of the Manning signing, based on what a friend that tried to get a couple was told.
