    "reasoning": "I've discovered something very surprising: the dataset contains 'BYE' and 'Clinched Playoffs' as GameStatus values, and these account for the null scores. BYE weeks aren't actual games - they're rest weeks where teams don't play. 'Clinched Playoffs' also appears to be a status marker, not a game. This means the dataset is treating non-games as game records. But I need to verify what these 'BYE' records actually represent - are they placeholder rows for each team's bye week? Let me check a sample of BYE records to understand this better.",
