Line movement: The spread seems suspiciously small for an undefeated BYU team at home against an inconsistent Arizona. This could indicate sharp money on Arizona.

Statistical mismatch: Despite BYU's record, they've been outgained by opponents in multiple games. Arizona may have an advantage in total yardage.

BYU's unsustainable luck: The Cougars have benefited from fortunate breaks and game scripts that may not continue, like defensive/special teams scores.

Arizona's talent: The Wildcats are considered very talented but haven't put it all together yet. There's potential for a breakout performance.

Day game factor: BYU has struggled significantly in day games since 2019 (5-14 record) compared to night games (28-3).
