But Eli Manning's 2010 was better and Rivers' considerably worse than the raw numbers show. Rivers had a whopping 4,710 passing yards, but many of them came when the game was already decided. Last year, the Chargers outscored their opponents by an average of 20 points in their wins and won six games by three touchdowns or more, both by far the highest figures among all teams that won eight to 10 games.
In high-leverage situations (plays with clutch value above 1.0), Rivers was just slightly above average, with a QBR of 56, whereas his QBR was 80 in blowout conditions. Manning, on the other hand, was more efficient. QBR estimates that Manning's completions added 107.0 points to the Giants last year, or 2.67 points per 100 passing yards; Rivers' completions added 108.5 points, or 2.30 per 100 yards.
