Short. "Very serious problems mounting every day. A year and a half is too much." Before the Court Once the Supreme Court agreed to hear the case, both sides submitted briefs. Flood's attorneys received a two-week extension from Justice Thurgood Marshall and submitted theirs in December 1971, while MLB responded at the end of January 1972. Goldberg's brief had eliminated the Thirteenth Amendment concerns entirely and focused on how the reserve system had become "drastically more restrictive" since its introduction and previous litigation. Paul Porter and Lou Hoynes responded to Goldberg's antitrust assertions by arguing that Flood's case was a labor dispute that should have been settled in a collective bargaining agreement (CBA) between league and union, not in court.

Porter came next, arguing for Kuhn and MLB in rebuttal that baseball was unique, even compared to other sports, in the antitrust context because of the portion of its revenues invested in player development through their extensive farm systems. Louis Hoynes, counsel for the NL, argued MLB's case. He placed great emphasis on the MLBPA, which he said "has in fact controlled this litigation from beginning to end", to suggest that the real goal of the lawsuit was to make
