Purdue's entire tournament run has been built on one premise: elite big men create easy baskets. Matt Painter's system is relentless in the pick-and-roll, with bigs catching the ball in space and making the right read to kick out to open shooters or finish at the rim. But Arizona has the one thing that stops that system: perimeter length that extends to the three-point line. Arizona's guards don't just defend the perimeter; they can recover to Purdue's bigs and contest their passes out of the post. Tommy Lloyd's Wildcats have spent the entire tournament proving they can make elite offenses uncomfortable, and Purdue's reliance on interior ball movement plays directly into Arizona's hands.

The AI model leaderboard shows GPT-4o, Gemini 2.5, and Perplexity Sonar Pro all recognize the matchup problem Purdue faces. Purdue's big men are generational, but they need space to operate. Arizona's defense doesn't give them space. According to the confidence calibration data, the AI models show high confidence in Arizona's ability to execute their defensive scheme because it's specifically designed to counter what Purdue does best.

Arizona's ability to keep Purdue's bigs off the glass in the first half determines whether the Wildcats can build an early lead. If Arizona can force Purdue into contested interior looks and limit their second chances, Purdue's offensive rhythm breaks down by halftime. Purdue can still win if their shooters get hot from three and Arizona's perimeter pressure creates space for them, but that requires a level of shooting consistency Purdue hasn't needed all tournament.

The prompt sensitivity analysis shows Arizona's defensive advantage holds up consistently across all AI model testing, regardless of how the matchup is framed.

Arizona wins 71-64. Purdue's Elite 8 run ends because Arizona's perimeter length and defensive activity create an environment where Purdue's interior dominance can't generate the rhythm and spacing they need. The source bias intelligence data shows consensus among GPT-4o, Gemini 2.5, and Perplexity Sonar Pro that Arizona's defensive system is the deciding factor. The upset detector shows this is a genuine matchup problem, not an upset.
