Philadelphia Eagles Week 13 Stock Report

If you thought the Philadelphia Eagles' stock had reached rock bottom after a 45-17 loss to the Tampa Bay Buccaneers, well, you were wrong. It hit a new low on Thanksgiving Day with a 45-14 defeat at the hands of the Detroit Lions.

The Eagles' stock as a team has never been further in the tank at any point during Chip Kelly's three-year run as head coach as it is now. The team's record is 4-7, and people are openly questioning whether Kelly's lost the locker room or could be fired at season's end.

Kelly has five weeks to prove he still has control of this team and show some semblance of improvement. As for his players, let's take a look at whose individual stocks are rising and falling.

Stock Down: DeMarco Murray

At one point this season, it looked like DeMarco Murray was turning a corner. Then again, judging from how long it takes him to turn the corner on the football field these days, maybe he still is.

If that's the case, Murray's performance against the Lions was a step back. The soon-to-be former NFL rushing champion carried 14 times for just 30 yards on Thanksgiving—a paltry 2.1 average.

Much of the problems in Philadelphia's ground attack begin up front with the offensive line. Then again, there's a reason Ryan Mathews is running the football so much better. Murray is leaving meat on the bone. He looks slow and frequently goes down on first contact.

Maybe it's last season's heavy workload, or maybe he was a product of the Dallas Cowboys offensive line. Whatever the case, Murray has not looked like the same player since joining the Eagles.

Stock Up: Sam Bradford

Can a player's stock rise without even playing? In Sam Bradford's case, absolutely. Any thought Mark Sanchez should replace him at quarterback is out the window after the offense has gone completely anemic with the backup at the helm.

Bradford was playing better than people realize. Dropped passes and poor protection are partially to blame for his poor numbers. Not only that, it doesn't take into account his improvement as the season has gone along, particularly in his last two games.

Bradford completed 72.1 percent of his passes for 8.7 yards per attempt with two touchdowns and zero interceptions in his last two games before the injury. As soon as he gets healthy, it's time for him to get back on the field.

Stock Down: Walter Thurmond

Walter Thurmond's move from cornerback to safety got off to a fast start in training camp and the regular season. However, the more time goes by, the more the sixth-year veteran's inexperience at the position has shown.

Thurmond was late getting help over the top on a touchdown pass to Calvin Johnson last week. He took a horrendous angle to the ball-carrier on Doug Martin's 84-yard run against the Tampa Bay Buccaneers the previous week. Unfortunately, these specific types of plays are becoming par for the course.

Thurmond is an extremely intelligent player, so there's no question he could improve if he were to remain at safety permanently. Regardless, the Eagles have been hurt in some big spots by the lack of instinct that comes from somebody who's familiar with nuances of the job.

Stock Up: Vinny Curry

At least somebody came to play on that Eagles defense the last two weeks. And of all people, it was Vinny Curry, who's been surprisingly quiet all season. Curry notched a pair of sacks against the Lions, more than doubling his 2015 total to 3.5.

The somewhat disappointing production is not entirely Curry's fault. The Eagles experimented with the fourth-year pro at outside linebacker, which isn't best suited for his skill set. His focus should be as a situational pass-rusher from the defensive end spot, where he racked up 9.0 sacks in limited playing time last season.

Now that Curry is sticking to what he's good at, the sacks are coming. A strong finish to this season could mean a big payday ahead in free agency come 2016.

Stock Down: Bill Davis

Any time the defense surrenders 391 rushing yards and 10 touchdown passes in the span of two games, the defensive coordinator is in jeopardy of losing his job. That's certainly the case with Bill Davis right now in Philadelphia, and he knows it.

While head coach Chip Kelly expressed confidence in Davis, the fact of the matter is the Eagles are 4-7, and somebody will likely have to play the scapegoat when this season ultimately ends in failure. Davis is the easy fall guy if Kelly is sticking around.

The worst part is Davis didn't really have any answers for the complete and utter defensive collapse in the past two games. It's not one player; it's just about everybody. Eventually, the coach is going to be held accountable.
