U.S. sports realized the money game since early 70's. So there were a lot of changes since then, its not like there are no old clubs, but not a lot who are successful. Plus, Football doesnt realize it, but the system of relegation is what keeps teams so competitive and builds a culture amongst fans, that is so lacking in US sports that the lower team owners, IMO almost always take undue advantage of fans, play one or two good players, others lame and still play in the same league, year after year and earn a lot of money!
Morale of the story, seriously, nothing like Football!!!
