age, and a smaller proportion ranked inferior relative to those in the NFL. In contrast, the expansion teams in MLB achieved greater success in average performance, attendance, and market value in the 1990s than the expansion teams in the other sports.
We suggest that the future growth and success of these sports leagues depend on team rivalries, the competitiveness of the teams, and the entertainment value of the sports to the public. The sport that offers the opportunity for average and inferior teams in small- and medium-markets to improve performance, that attracts fans from their local and regional areas, and that broadcasts into international markets, will dominate the sports industry in the early twenty-first century. 6
We also concur with sports researchers Dennis Zimmerman and William A. Cox that leagues should ease restrictions on the relocation of franchises. While they concede that fans and public officials in cities loosing a team would mourn the loss, their counterparts in the newly enfranchised cities "would be jubilant." Although fan satisfaction remains difficult to quantify, Zimmerman and Cox contend that it may increase after the move. Accordingly, owners move their teams to sites with better prospects for earning profits. Thus, the owner anticipates more fans supporting the team at the new location. 7
Besides relaxing constraints on franchise relocation, MLB should also ease the restrictions on the number of teams and situating new ones in the most lucrative markets that have large populations and "valuable local radio and television rights." As Zimmerman and Cox put it: "Increasing the supply of franchises in large-revenue markets could make the large-revenue clubs economically similar to small-revenue clubs. If competitive balance is sensitive to equality of financial resources, this would be an effective policy." 8
