Article Assessment:
Credibility Score: 75/100
Bias Rating: 55/100 (Center)
Sentiment Score: 60/100
Authoritarianism Risk: 30/100 (Generally Democratic)

Bias Analysis:
The article presents multiple viewpoints and quotes directly from the involved parties, maintaining a relatively balanced approach. However, the inclusion of Trump's involvement and the focus on U.S. perspectives slightly tilts the narrative, though not significantly enough to be considered partisan.

Key metric: International Sports Diplomacy

As a social scientist, I analyze that this article highlights the intersection of sports and politics, particularly in the context of international competition. The involvement of a former U.S. President in team selection discussions for the Ryder Cup demonstrates the high-profile nature of this event and its potential impact on national pride and international relations. Bradley's decision to prioritize team performance over personal ambition, despite high-level encouragement, reflects a commitment to professional integrity and team dynamics. The disagreement between Bradley and McIlroy on the feasibility of a playing captain role underscores the evolving nature of sports leadership and the tensions that can arise in international competitions. This situation may influence perceptions of U.S. sports diplomacy and team cohesion on the global stage.
