If you look solely at the monetary side , each of these guys cost over $100 million over the years of their contract. Those costs have to be justified in terms of ticket sales, tv revenue, ad revenue, concessions and increased value of the franchise. Since the contractual cost is only part of the total cost of runnning the club, it all needs to be brought into balance. Most clubs are still making money but a deterioration in the main sources of revenue could indeed make these salaries a thing of the past. Owners need to stop the ridiculous overspending on some of these guys.
