When numbers get that big they are just numbers. 10 mil or 18 mil what is the difference? Unless they have some serious addictions they will NEVER spend that much money in their lives.
All this talk from these clowns saying they have short careers and all that. Well most people do not make a million dollars in their lifetime working, yet these guys can't seem to scrape by on 5-6 mil a year?
Besides the NFL is all about upfront money and signing bonuses, they could wipe their azzes with the so called contract they sign. So that is a catch-22, they make a lot of money, and they also get a lot of money up front to do with as they please. So with the right investments and management that upfront money could make them an extra 10-20% for a season. So that 5 mil signing bonus could turn into 5.5 to 6 mil by season end.
But again when it gets that high they are just numbers, it is like monopoly money. Aslong as they have a house or two, a couple nice rides, every game for playstation or xbox or whatever game is hot these day, a nice home theater, what else do they need money for? Maybe some bling. But I can't picture Brady or Manning sportin a 2 carat earring anytime soon.
