Both the Detroit Lions and Philadelphia Eagles have struggled with turnovers so far this season. Both teams are toward the bottom of the NFC in turnover differential. The Eagles actually rank last in the NFC at -7, while the Lions are 13th at -3.
Given the struggles these two teams have had with turnovers, which team wins the turnover battle on Sunday could play a big part in deciding the result of the game. Specifically for the Lions, they need to take advantage of Philly's turnover issues and capitalize on their mistakes. The Eagles have had six interceptions and eight fumbles already this season, meaning they give the ball up quite a bit. Defensively, the Lions have only forced three fumbles through four games (they have zero interceptions). They need to start creating more turnovers, especially against the Eagles.
On the other side, the Lions have turned the ball over six times this year (four picks and two fumbles). Philadelphia has only recovered one fumble, but they have six interceptions. Their turnover differential would be much worse if not for their penchant for interceptions, so Matthew Stafford will have to be smart with his passes on Sunday.
At the very least, the Lions can't let Philadelphia improve their turnover differential this week. Ideally, the Lions would finally get their own turnover differential out of the negatives with a strong showing. This is something I will be keeping an eye on in Sunday's game.
