You have to get hotels for 105 football players, coaches (maybe their families?), football team staff (e.g. equipment managers, trainers), athletic department folks, cheerleaders, and Cy. Then you have to damn near double that for the band. Since this is in NYC, you probably don't want to put them in a dangerous area, either, which is going to drastically increase the hotel costs.
Now you have to give them all money to eat, pay those employed by the Athletic department, and arrange transportation, be it by plane or bus.
