Rather than just an even split of the income from national broadcasting, as is the case now, Costas wants a sharing of the gate receipts and even local-broadcasting revenue. It would reduce money's role as a determinant of who is competitive and who isn't. Costas also wants some constraints on salaries, but knows that the Players' Association will never accept a simple salary cap. Neither change would be simple to achieve. Large-market owners are unlikely to agree to give up their enormous advantages, at least until there is no other way.
Costas also deals with non-money issues.
A better idea would be to expand the leagues by two more teams, create four divisions in each of the American and National Leagues, and let the pennant winners contest semi-finals, championship and the World Series. Overall, Fair Ball presents a good case that major league baseball is ailing. Even though baseball had record attendance in the 2000 season, the undeniable and growing uncompetitiveness is ultimately a form of dry rot for fan support. And while you might question whether Costas' reforms would work, his book provides a readable and balanced introduction to the problem areas. For fans who are disgusted at the prospect of a World Series that, this year at least, won't leave New York City, Fair Ball is worth reading.
