The Eagles worked out wide receiver David Gettis and linebacker Nathan Williams, a source confirmed.

Gettis (6-3, 217), a sixth-round pick by the Panthers in 2010, had 37 catches for 508 yards and three scores his rookie year. A torn ACL in August of 2011 derailed his sophomore campaign, and he was bothered by an injured hamstring in 2012. He was released with an injury settlement earlier this month after hurting his hamstring again this preseason.

Williams ( 6-3, 240) had 12 sacks and 24 tackles for a loss at Ohio State. He underwent microfracture surgery on his knee in 2011 but was able to play for the Buckeyes in 2012.

After two strong showings, what happened to the Eagles’ offensive line against the Chiefs? And what does it mean going forward? We take a look, using the All-22 film.

With a trip to Denver looming and back-to-back losses in the rear-view mirror, finding positives this week may prove to be a bit challenging for Eagles fans.

But there’s one simple reason to be optimistic: Chip Kelly and company are playing in the worst division in football. The Cowboys, Eagles, Redskins and Giants are a combined 1-7 against non-NFC East teams.

After this weekend’s matchup with the Broncos, three of the Eagles’ next four games are against division foes. Keeping that in mind, now seems like a good time to check in on the state of the NFC East.

The tight end position was expected to be a major component of the Chip Kelly offense. All signs pointed in this direction.

He moved quickly to sign free-agent James Casey to a three-year, $12 million deal, then used the 35th overall pick in April’s draft on Zach Ertz. He spoke of using three tight-end sets to “smash” the opponent. Even introduced a four tight-end look this preseason.

It is a surprise, then, how little Kelly has featured his tight ends through three games.

When Chip Kelly was asked to evaluate Michael Vick’s performance against the Kansas City Chiefs, the word he used was okay.

Okay is generally coach-speak for: He didn’t play well, but it’s unfair to place all the blame on one guy.

And that’s true. The offensive line had too many issues. Wide receivers struggled to get open consistently. The defense couldn’t get off the field during an 8-minute, 15-second stretch in the fourth quarter. And special teams suffered a variety of miscues.

But one week after throwing for 423 yards and completing nearly 64 percent of his passes against the Chargers, Vick was just 13-for-30 with three turnovers against the Chiefs.

What were some of his issues? Let’s take a look, starting with his first-quarter interception.

Michael Vick only completed 43.3 percent of his passes against the Chiefs on Thursday. The last time he had a completion percentage that low was 2006, when he went 9-of-24 (37.5%) against the Saints.

He made poor decisions with the football at times and too many of his throws were off target.

Chip Kelly, though, seemed to come down harder on the offensive line than he did the quarterback following the 26-16 loss to Kansas City.

The Philadelphia crowd started giving Chiefs cornerback Sean Smith the business as he took a seat on the Lincoln Financial Field grass. Michael Vick‘s 13-yard pass to Riley Cooper midway through the third quarter had brought the Eagles inside the red zone. Smith, in coverage on the play, began grabbing for the back of his leg once Cooper stepped out of bounds before sitting down to wait for his trainers.

“I knew it was coming ,” said Smith, via the Kansas City Star. “Everybody thought I was faking, but I had to get an IV ― I’ve got the proof right here,” he Smith said, pointing to a bandage on the inside of his arm.

“It shows how fast-paced that offense is. It’s crazy, you can’t really practice it. So when you see it for the first time, you don’t really know what to expect.”

This has become a recurring theme through the Eagles’ first three games. A player goes down with cramps, the up-tempo drive runs into a red light, and it’s impossible to know for sure whether everything is on the up-and-up.

Chip Kelly has used some version of the same line several times since he was hired as the Eagles’ head coach back in January.

“If you weren’t in the room with Amos Alonzo Stagg and Knute Rockne, then you stole it from somebody,” Kelly says. “We didn’t invent this.”

It’s Kelly’s way of denying that he’s some kind of innovator or revolutionary, labels that make him uncomfortable.

Also, there’s truth behind what he’s saying. In Week 1 against the Redskins, Jon Gruden suggested that the Eagles scored a touchdown to DeSean Jackson on a play Kelly stole from the New Orleans Saints (although it was really one that several NFL teams run).

And the guess here is that Kelly will be installing one specific play he saw from Andy Reid and the Chiefs Thursday night.

Alex Smith failed to get the ball downfield all game long, completing just one pass that traveled more than 10 yards from the line of scrimmage, per Pro Football Focus. But the Chiefs were able to use a wrinkle to convert a couple third-and-longs with yards after the catch.

Are the national media turning on Chip Kelly? Here’s a roundup of what they’re saying about the Eagles after their 26-16 loss to the Chiefs.

Because we have some extra time this week, we’ll split up the All-22 pieces into a bunch of shorter posts.

First, let’s start with the failed two-point conversion in the first quarter.

Chip Kelly’s explanation on Friday: “If you get an opportunity to get an extra point, and in this game, every game’s close. If you get a chance to steal a point here or there, in the long run, it can really benefit you.”

Here’s a position-by-position look at what we saw after reviewing Thursday night’s game.

Chip Kelly‘s phone went off during the middle of his day-after press conference Friday afternoon.

“Sorry guys, hold on,” he said as he worked to stop the ringing, to no avail. Finally, after a little fumbling, he slid the device into his pocket and returned to taking questions.

“Can’t even get a press conference straight,” he said.

Such is the life of a rookie coach in the midst of his first losing streak.

After an explosive start back on September 9 against Washington, Kelly’s Eagles have crashed back down to Earth. Turnovers, mental errors and defensive breakdowns have all been a part of it.

Kelly’s approach has also come under the microscope in a few instances.

From a missed field goal to a failed two-point conversion try to their own version of the butt fumble, the Eagles had their share of bloopers and miscues in a 26-16 loss to Andy Reid and the Chiefs.

Let’s take a closer look at what went wrong on these plays.

Here’s a look at how Chip Kelly divvied up playing time against the Kansas City Chiefs, with notes on Vinny Curry, Brandon Graham, Zach Ertz and others.

The biggest boos from the crowd at Lincoln Financial Field Thursday night came when fans thought the Chiefs were trying to employ a familiar tactic to slow the Eagles’ offense down.

On separate occasions in the second half, cornerbacks Sean Smith and Brandon Flowers went down with injuries while the Eagles were driving. But in a league that’s as violent and physically taxing as the NFL, it’s pretty much impossible to separate real from fake.

“Once you stop the momentum we’re having, and when we are coming back and moving the ball, I think the [Chiefs’ defense] was getting tired,” LeSean McCoy said. “[Injuries] give them time to get their breath back. Who is to say if they were faking it or not? People get hurt during the game.”
