Here's a look at the first-half impact of the Philadelphia Eagles' draft class:

Derek Barnett, DE, first round: The 14th overall pick out of Tennessee has been a steady part of Jim Schwartz's defensive line rotation. He's been picking up his productivity of late, and now has 2.5 sacks and five tackles for loss on the year. Plenty of promise here, but expectations are always heightened for first-round picks. Grade: Average

Sidney Jones, CB, second round: Jones ruptured his Achilles during his pro day and is still on the mend. While there's a chance he'll be physically able to play this season, the Eagles could go the conservative route here with his long-term future in mind. Grade: Incomplete

Rasul Douglas, CB, third round: With Jones still recovering and Ronald Darby sidelined with a dislocated ankle, Douglas has gotten a good amount of work opposite Jalen Mills. There have been some inconsistencies, but Douglas has two interceptions and nine passes defended in eight games. He looks like he belongs. Grade: Above average

Mack Hollins, WR, fourth round: Hollins has been targeted by quarterback Carson Wentz 10 times. He has caught nine of them for 172 yards (19.1 average) with a touchdown and six first downs. Add in his special-teams contributions, and the Eagles are getting value out of this fourth-round pick. Grade: Above average

Donnel Pumphrey, RB, fourth round: He is on injured reserve with a hamstring injury, so you can argue an incomplete grade might be the way to go here. But he barely made the 53-man roster after a quiet summer, perhaps saved by the fact that the team invested a mid-round pick in him. Grade: Below average

Shelton Gibson, WR, fifth round: Similarly, Gibson was right on the bubble. He had drop issues during training camp and was unable to climb up the depth chart. The speedster has not appeared in a game to this point in the season. Grade: Below average

Nathan Gerry, LB, fifth round: Gerry spent the summer making the transition from safety to linebacker. He was not on the initial 53-man roster, but was promoted from the practice squad in mid-October when safety Chris Maragos was placed on injured reserve. He has not appeared on the stat sheet to this point. Grade: Below average

Elijah Qualls, DT, sixth round: Qualls has been active for a handful of games and has a pair of hurries and a tackle. This defensive line is deep and talented, so it's no knock on Qualls that he hasn't received more playing time as a sixth-round pick. Grade: Average
