Is there a salary cap for A-League franchises? If no, let's imagine some mega-millionaire suddenly decides he wants to own a professional soccer team. He's an egomaniac, so he has no interest in MLS and single entity ownership. Instead he buys an A-League expansion team for NYC and builds "Stad de NYC" - a 40,000 seat stadium built on Queens waterfront featuring magnificient views of Manhattan Skyline. The team is loaded with talent - the best players money could buy, from all over world. I realize this will never happen but what's to stop me (oops - alright I just bought my Mega -Million lottery ticket and can't stop dreaming) from doing it if I've got the bucks to make it happen? How terrible/great for professional soccer in U.S would this be?
Have at it. It had better be a big lottery, considering what it's going to cost you to build the stadium and get the talent. Nothing's stopping you, I guess. Except that little nasty thing called This Is How Reality Works On This Planet. No, the A-League doesn't have a salary cap. Rampant salary inflation is not one of the A-League's major problems.
