Chip Kelly pointed out that his offense was on pace to break records early in the season. In the past two weeks, though, the offense hasn't scored a single touchdown.
Kelly didn't take this as a sign that the league has adjusted to his system.
"I don't think people have figured out [our offense]," Kelly said. "You can turn the tape on and watch six games of whoever you play, I can tell you what they're going to do. I can tell you what Peyton Manning is going to do. You still have to stop them. They still have to execute."
When Jason Avant was asked after Sunday's game what has happened with the offense, the Eagles receiver gave credit to defensive coordinators for analyzing what the Eagles do well and adjust accordingly. Avant said Kelly must and will adjust, and the players need to make plays.
"It's still about executing," Kelly said. "I think everybody kind of knows going into the game plan, you're not going to surprise people eight games into the season. We have to run the right depth on our routes. We have to catch the ball when it's thrown to us. We have to put the ball on people when people are open. We have to hit the hole when the hole is there. We have to create a hole if the hole is not there. That's just executing football."
Kelly said the Eagles offense was "successful for six games." He continued to point to the "quarterback instability" and noted that the Eagles needed to use their third quarterback during the past two games. That's a "difficult proposition" because that quarterback does not have the accumulation of practice reps.
When there's instability at quarterback, Kelly said the offense needs to lean "on something else that can help us get through those murky waters." That has not happened. The running game has stagnated, and the receivers are not making plays.
Kelly pointed to small mistakes that can back up a drive. One example is when DeSean Jackson ran sideways and not forward as he approached the first-down marker. One more yard on was the difference between extending the drive and punting.
LeSean McCoy also ran sideways on a 3rd-and-1 in the third quarter for no gain, although he did not have much space. But Kelly was clear that the Eagles' "playmakers got to make plays." McCoy and Jackson are the top "playmakers" on offense.
"It's not all on the quarterback," Kelly said. "It's on all of us. We have to do a better job as a total group. I have confidence in the group. It was the same group for six games that we were on track to set records. It's not like we're going to throw the baby out with the bath water and start over again and say we're going to do something new here."
Nick Foles is undergoing an ImPACT test on Monday. If he passes that test, he must then be cleared by an independent neurologist before he can resume practice.
Kelly did not want to speculate on the quarterback situation until he knows the status of Vick and Foles. He does not believe Vick will be ready for Sunday's game against the Raiders, though. Vick had an MRI scheduled for Monday.
