Saquon Barkley was disappointed with the Eagles offense during their 24-15 loss to the Chicago Bears on Friday. After the game, the three-time Pro Bowler sounded the alarm on their offensive struggles during an interview with NBC's John Clark.Saquon Barkley highlighted how the offense needed to improve its focus on the field, as a lack of it can negatively impact the outcome of a game. He also highlighted that it is the collective responsibility of all offensive players for any mistakes they make during their play."Yeah, group focus. I think it's group focus," Barkley said. "It starts with that. We've got to come together. We have to focus. When you're not focused, it can hurt you. I had a drop today. A drop is literally a lack of focus. It has nothing to do with talent. Nothing to do with, 'I can't catch the ball.'"We have multiple spots like that. Sometimes, it comes up and gets up. And we just got to be better. We keep talking about it. We keep saying it. We are addressing it. And it's just not clicking right now. That's the truth. I hate to say it. We've got to figure it out. And we got to figure it out soon, to be honest."Against the Chicago Bears, Saquon Barkley had 56 yards on 13 carries and no touchdowns. It was his fourth consecutive game that he failed to find the endzone with a rushing touchdown. So far this season, the running back has tallied 740 yards and four touchdowns rushing.Following their Week 12 loss to the Cowboys, Barkley highlighted how he's been feeling "nonexistent" this season under new offensive coordinator Kevin Patullo. Nick Sirianni's team is ranked No.21 in terms of a running offense, averaging 110.5 yards and 12 rushing touchdowns.Saquon Barkley opens up about the biggest takeaway from the disappointing 24-15 loss to the Chicago BearsLast year, Saquon Barkley put up his best season in the league, recording 2,283 yards and 15 TDs rushing.
