Final answer:
Without specific text from the speaker, the exact purpose isn't clear; however, contextual clues suggest a persuasive intent, likely to mobilize the audience towards a popular opinion or action related to sports.
Step-by-step explanation:
The purpose of the speaker needs to be determined from the context of the speech or text they are presenting. When assessing the purpose, questions to consider include: Is the author writing this to persuade, to inform, to entertain, to describe, or to explain? What does the author want the audience to do? Lack of specific text from the speaker makes it difficult to determine the exact purpose but the context given, such as trying to converge support for a team or getting individuals to attend games, hints towards a persuasive intent. Additionally, the use of the bandwagon approach in one of the provided contextual statements indicates a persuasive effort to align the audience with a popular opinion or trend.
