Tokenization of Professional Player Contract

Spencer Dinwiddie of the Brooklyn Nets basketball team is planning to tokenize his $34 million NBA contract extension. The Three year $34 million NBA contract extension, Dinwiddie is reportedly going to sell digital tokens tied to the contract, wherein investors in the offering would receive principal and interest. This is a bold and interesting move from Mr. Dinwiddie. If this is a success for him, what is to stop other athletes from doing the same? And if say a billion dollars worth of salary from just the NBA follows the same path, how will this change the world of blockchain from here on out?
