Dado un texto de referencia sobre los Mid-South Grizzlies contra la NFL, ¿cuál fue el resultado del pleito?
Mid-South Grizzlies contra la NFL, 720 F.2d 772 (3d Cir. 1983), fue una demanda presentada por John F. Bassett, propietario de los Memphis Grizzlies de la Liga Mundial de Fútbol, contra la Liga Nacional de Fútbol, alegando que la NFL violaba las leyes antimonopolio al negarse a admitir a su club en su liga.

El tribunal consideró que la NFL no había adquirido ni mantenido ilegalmente su poder de monopolio y que la negativa a expandirse a Memphis no contribuía a su mantenimiento. Explicó además que dicha negativa era en realidad procompetitiva porque dejaba la zona de Memphis abierta a ligas rivales Cuando se resolvió el pleito, Bassett había pasado a fundar los Tampa Bay Bandits de la United States Football League, mientras que Memphis recibió los Memphis Showboats de la misma liga. De este modo, el caso pasó a ser discutible. (Por cierto, la USFL presentaría una demanda antimonopolio mucho más famosa contra la NFL unos años más tarde, que aunque se resolvió con éxito en contra de la NFL, sólo proporcionó una somera indemnización monetaria a la USFL; irónicamente, Bassett se opuso abiertamente a esa demanda).
El tribunal dictaminó que la NFL no había adquirido ni mantenido ilegalmente su poder de monopolio y que la negativa a expandirse a Memphis no contribuyó a su mantenimiento.
Given a reference text about the Mid-South Grizzlies vs NFL, what was the result of the lawsuit?
Mid-South Grizzlies v. NFL, 720 F.2d 772 (3d Cir. 1983),[1] was a lawsuit filed by John F. Bassett, the owner of the World Football League's Memphis Grizzlies against the National Football League claiming that the NFL violated the antitrust laws by refusing to admit his club to their league.

The court found that the NFL had not acquired or maintained its monopoly power unlawfully and that the refusal to expand to Memphis did not contribute to its maintenance. It further elaborated that such refusal was actually procompetitive because it left the Memphis area open to rival leagues.[2] By the time the lawsuit had settled, Bassett had gone on to found the Tampa Bay Bandits of the United States Football League, while Memphis received the Memphis Showboats of the same league. As such, the case effectively became moot. (Incidentally, the USFL would go on to file a much more famous antitrust suit against the NFL a few years later, which while successfully decided against the NFL, provided only a cursory monetary award to the USFL; ironically, Bassett was an outspoken opponent of that lawsuit.)
The court ruled that the NFL had not acquired or maintained its monopoly power unlawfully and that the refusal to expand to Memphis did not contribute to its maintenance.
