This study presents a structured model to investigate whether sports fans' team identification and organization-public relations (OPR) directly affect their attitudes toward their favorite teams or related behavioral intentions. In addition, it examines which antecedents, such as sports media consumption or duration of being a fan, affect team identification and OPR, and investigates whether gender works as a moderator in the model. An online survey was used and a total of 673 responses of the National Football League (NFL) fans were analyzed. The results of path analyses show that sports media consumption directly affects team identification and OPR, while the duration of being a fan did not significantly influence OPR and had only a small effect on team identification. Moreover, the degree of identification and relational perception of an NFL fan directly affect attitudes toward his or her favorite team. Finally, a person's attitudes toward the favorite team directly affect his or her purchase intention of team-related products and attendance intention. Among paths in the proposed model, only one path, from attitude to attendance intention, was significantly different between the male and female groups.
