Which factor is least likely to affect the outcome of a roller derby playoff?

The popularity of the team on social media is least likely to affect the outcome of a roller derby playoff. While a strong social media presence can help with fan engagement, sponsorships, and community support, it does not directly influence the performance of the team on the track. The skills, strategies, and teamwork demonstrated during the game are the key factors that determine the outcome of matches.

In contrast, team communication is crucial as it allows players to coordinate strategies and respond quickly to in-game developments. Adequate practice time helps teams develop their skills and build teamwork, which are essential for success in a competitive playoff environment. Individual player stress levels can also significantly impact performance; high stress can affect concentration and execution of skills during critical moments in a game. Therefore, while social media presence can enhance overall team dynamics, it does not have a direct bearing on the athletic performance during the playoff matches, making it the least impactful choice among the options given.
