The Knicks and Rangers play in MSG! There are so many corporate seats, and seats sold to travelers that those clubs could trot out teams of U14 kids and there will be 18k in attendance. You cant compare it to the demand for an MLS ticket. People will go to YS to watch the Yankees, but not necessarily NYCFC. You can better compare the Red Bulls to the Devils and Islanders. When those teams are poor attendance drops. Not sure if the Devils ever have solid attendance.
Devils attendance has been so much better since moving to Newark because you use to be only able to drive to games at the Meadowlands.
Also their attendance has been solid even with the team being basically horrible for an entire decade before last season.
I'm a season ticket holder there as well so I'm at every game, this and last season have had tons of sell outs and packed crowds. Been much better attendance than our Red Bulls.
