Some conventions that are present in a sports drama are having a sports competition, an athlete, a narrative, a constant state of emotion, disruption, resolution, success, and failure. We do not challenge these conventions but we do comply with them.
In the film there is a sports competition which is the state finals where all the scouts are going to be. We also establish characters and create an emotional connection between the viewer and characters. We do this by demonstrating how Elena is financially unstable and is struggling. This connection will drive the viewer to be more attached and have her success in the ending to become a lot more impactful.
Although the other parts are not being included, we comply with the genre conventions by having her go through an injury, but recovers right in time fro her competition. Obviously, like most sports dramas, it would end with a positive ending; Elena winning states and entering the college of her dreams.
