Sunday's game against the Arizona Cardinals will mark the first time in his NFL coaching career that Chip Kelly will face a team outside of the division for a second time.

The Eagles first go-around with the Cardinals was a successful, as Kelly managed to squeak out an important 24-21 win.

"Yeah, we always look at everything," Kelly said when asked if he can use that game to his benefit. "If it's a whole new coaching staff, then sometimes that doesn't benefit you, but if it's got the same coaching staff, and obviously they do, so we looked at it."

Not much has changed between the two teams, at least not on the Cardinals side of the ball. Arizona returns the same weapons on offense they had last season, and still have the same playmakers like cornerback Patrick Peterson on defense.

So what can the Eagles learn from re-watching their win over the Cardinals last season? Here is a look at what stood out after re-watching the tape.

Bradley Fletcher

One very concerning sign in this game was the tackling of cornerback Bradley Fletcher.

On these two plays, Fletcher was in great position to take down Cardinals receiver Larry Fitzgerald, a matchup he will see once again this weekend.

He whiffs on that attempt, allowing Fitzgerald to go right by him. He was even better set up for his attempt, but once again fails to get the job done.

Fletcher was credited with just five missed tackles last season by Pro Football Focus, the least of any member in the secondary. His tackling has improved this season as he has just one missed tackle in six games, an encouraging sign heading into this weekend.

Running game

The Eagles were the best team in the league running the ball last season, and it showed in the way the Cardinals respected the play action fakes.

This red zone play Kelly calls is nothing special, but it was set up by a season of sticking to the run. Tight end Zach Ertz is going to run to the corner of the end zone, and the Cardinals have good coverage for the play.

After the snap, however, quarterback Nick Foles fakes a pitch to running back LeSean McCoy, freezing nearly every defender on the Cardinals for a second, and diverting their attention off of Ertz.

That second is a big one, as it allows Ertz to get behind the defenders and a step on the safety. The result is an easy touchdown for the Eagles.

Ertz had a big day against the Cardinals, catching two touchdowns. Going into this weekend, offensive coordinator Pat Shurmur wouldn't go into details on if Ertz can expect another heavy workload.

"I think each week the tight ends are involved," Shurmur said. "Certainly."

Although he won't admit it, Shurmur might not be as successful this year utilizing the tight ends. The play above worked because of how much respect the Cardinals had for the running game. Given the struggles on the offensive line this season, it is hard to see that same respect being paid — something that could impact the tight end's production.

Red Zone

Not everything called by Kelly in the red zone worked out last year. Remember this gem of a play call?

That is receiver Brad Smith in at quarterback, a play that resulted in a sack. It's hard to imagine we will be seeing this play again, especially with the struggles in the red zone so far this season, something Shurmur said the team worked on during the bye week.

"I think we spent a lot of time last week looking at situational football," Shurmur said. "We looked at what we'd done the first half of the year, so to speak, in the red zone and on third downs. A lot of it comes down to not one common theme. We like to run the ball in the red zone, as you know. We try to stay balanced in terms of whether we're running or throwing it. We’ll throw it or run it on any down and distance. I think it just came down to us being sounder and executing better in most situations."

Patrick Chung

Perhaps the most encouraging sign for the Eagles this season is that safety Patrick Chung will be nowhere near the team's game in Arizona.

Chung had a brutal game against the Cardinals last season, spearing cornerback Brandon Boykin at one point by accident, freeing Fitzgerald for the touchdown.

Chung would end up getting cornerback Cary Williams later in the game as well.

The look on Williams' face is priceless. Having Malcolm Jenkins in there over Chung should be a major advantage for the Eagles this time around.

Nate Allen

Nate Allen has had an up-and-down season so far, much like the rest of the secondary members. Last season, the good and the bad of Allen showed up against the Cardinals.

First, let's take a look at the bad.

Allen is kind of stuck between a rock and a hard place here, as he has Fitzgerald running underneath him. Given the damage Fitzgerald usually does to the Eagles, it is hard to blame him for trying to jump up and double him.

That decision, however, let receiver Malcolm Floyd get behind him and into the end zone wide open for a touchdown.

While his instincts burned him on that play, Allen did a nice job on a play later in the game that ended up in an interception off of quarterback Carson Palmer.

As you can see, Allen has his eyes on Palmer, and waits for the throw to be made before getting back to make a play on the ball.

It is a bad throw by Palmer, as he puts too much under the ball. Still, Allen had to be in position to make the play, which he does.

Nick Foles

One word to describe Foles' play both this season and against the Cardinals last season? Reckless.

Although is final stat line was impressive that day -- 21 of 34 for 237 yards, three touchdowns and no picks -- Foles could have easily had a disastrous game if nearly every ball didn't bounce his way. The Cardinals game, in some ways, was a preview of what Foles has played like this season, but with much less luck.

Look at the way Foles is scrambling in the pocket with the ball out to his side. He looks like running back LeSean McCoy, who has a bad habit of carrying the ball away from his body, but is able to get away with it.

This season, Foles has fumbled the ball four times, losing three of them.

Foles also had a number of balls nearly intercepted. A consistent theme on the passes Foles nearly had picked off was that he was almost brought down before letting the ball fly.

On this play, Foles takes a hit early in the play, but recovers and whips it down the field to a very much covered receiver DeSean Jackson (remember him?)

It is hard to know how much time Foles took to survey the field, but he decides where to throw the ball less than a second after being hit. The result is a near interception that Jackson has to knock away.

The same thing happened on this near interception to Ertz. It takes a great play from the tight end to knock the ball away.

His teammates weren't able to prevent his interception, however. Once again, Foles is being hit and nearly sacked before he even starts to throw the ball. Given the time on the clock and the situation, even attempting a pass is questionable.

The throw is especially risky when you see what Foles was looking at. Jackson is covered by Peterson, who nearly picked off a pass earlier in the game.

The pass was intercepted by Peterson, but in what was one of the biggest moments of last season, it was called back due to defensive holding. Had that ball been intercepted, and the Eagles lost the game, who knows how there season would have turned out.

This season, Foles hasn't been getting those lucky breaks, and receivers haven't been able to knock away every interception. Some of the flaws that Foles showed last season against the Cardinals have reared their ugly head this season, especially his habit for recklessly throwing the ball up and hoping something good happens.

This weekend, Foles — along with a number of other players highlighted above — will have to be better than he was last season if the Eagles plan on once again beating the Cardinals.
