We are doing a project where we pick a sports team and we must calculate the revenue and salaries of the players. Then we are asked to explain how a sports team can possibly lose money. Now, I have all of that but I am stuck on this last question, "WHAT ARE THE FACTORS(NEGATIVE AND POSITIVE) THAT CAN EFFECT THE OPERATING BUDGET?". I really don't get this... Ms. Sue? XD

Low ticket sales

High maintenance costs
Overpaid players and coaches
