The Philadelphia Eagles ran 53 plays on their way to 322 yards and 21 first downs in the first half in Week 1.

The Eagles played as fast as any team in NFL history, but Chip Kelly believes they can play faster.

“I felt like it was slow,” Kelly said Tuesday.

“I’m not joking,” Kelly said. “We need to do a better job. We left the ball on the ground too much. We didn’t get the ball to the officials. We could have sped things up from a process in between plays. That’s something we need to work on.”
