When analyzing the seasonal data, targeting the lower projection on passing yards for both quarterbacks might be the statistical play. San Francisco 49ers signal-caller Brock Purdy is currently averaging 239.2 passing yards per game, which falls short of his 249.5-yard line. On the visiting sideline, Washington Commanders quarterback Jayden Daniels is posting just 153.0 passing yards per game, sitting significantly below his set total of 209.5 yards.
In the ground game, Christian McCaffrey’s rushing prop is set at 61.5 yards, but the star back has averaged 57.2 rushing yards per game so far this year. Similarly, Washington’s Rachaad White is averaging only 29.5 rushing yards per game through the early stretch of the season, indicating that the lower selection for his 47.5 rushing yards prop is well supported by recent box scores.
