The Eagles played their first 60 minutes of football since winning Super Bowl LII and it was underwhelming to say the least. Nate Sudfeld started at quarterback and most of the Birds' marquee players spent the night on the sidelines sporting baseball caps. However, there were still some things to take away from the Eagles' loss to the Steelers.
Here's a quick look at some players who helped/hurt their stock on Thursday night.
Up: Fletcher Cox
It took just one play for Cox to announce his presence with authority. The three-time Pro Bowler has made it clear he wants to win Defensive Player of the Year in 2018 and his first-quarter tackle for loss proved he's as dominant as ever. With the Eagles looking very thin on the interior of their defensive line, Cox having a career year would be huge for the Eagles' continued success.
Down: Rasul Douglas
Douglas had a nice interception, but he was beaten twice for touchdowns Thursday night. Douglas has a lot of talent and played well during stretches last year, but his inconsistency remains the biggest issue facing his game. The second-year player is still behind Jalen Mills, Ronald Darby and Sidney Jones on the depth chart, so barring injury, he still has time to develop. In a perfect world, he can step into a bigger role in 2019 after Darby leaves in free agency.
Up: Eagles running backs
The Eagles built their offense around a powerful running game last year and, if last night was any indication, the Birds will boast a strong rushing attack once again. Darren Sproles was inactive, but both Jay Ajayi and Corey Clement strung together some nice carries early in the game. Even Josh Adams and Wendell Smallwood had some decent touches. The Eagles' carried five running backs at times last season, but with Ajayi, Clement and Sproles already locked in, it will be interesting to see how the bottom half of the depth chart shakes out.
Down: Tre Sullivan
Sullivan was a camp darling and seemed like the favorite to be the third safety on the roster before the signing of Corey Graham earlier in the week. However, for a guy who is fighting for a roster spot, Sullivan's effort on Juju Smith-Schuster's touchdown catch.

It seemed like Sullivan had a chance to catch the receiver, but he pulled up early and let him walk in the end zone untouched. This play will definitely be brought up in this morning's team meetings.
Up: Dallas Goedert
Goedert looked as-advertised on Thursday night, catching four passes for 66 yards and a touchdown. The rookie looked comfortable running routes and finding soft spots in the Steelers' zone coverage, but did drop a pass in the first quarter. Zach Ertz sat out last night's game and it's easy to imagine Doug Pederson salivating over the opportunity to deploy Ertz in Goedert in two tight-end sets.
Down: Isaac Seumalo
A lot has changed for Seumalo in the past year. He lost his job as the starting left guard early last year and was buried on the depth chart behind Stefen Wisniewski and Chance Warmack, he had to transition to center. However, Seumalo looked lost at center last night, sending a snap high over Joe Callahan's head, nearly causing a turnover. At this point, it's hard to imagine him making the team.
Up: Shelton Gibson
When Gibson was drafted last year, his upside was based purely on his top-end speed and his ability to develop into a deep threat in the NFL. Gibson struggled to make an impression last preseason, but he showed some elusiveness on a kick return and capped off his night with a 63-yard touchdown. The Eagles certainly aren't hurting for talent at wide receiver, but if Gibson can contribute on special teams and make opposing defenses respect his big-play capabilities, he can carve out a nice little role on this team.
