GREEN BAY, Wis. -- Here's a look at the first-half impact of the Green Bay Packers' draft class:

Kevin King, CB, second round: The Packers are grooming King to be their No. 1 cornerback, but it’s going to take some time. He hasn’t made any splash plays yet, but he’s getting valuable experience paired with veteran Davon House as the two starting corners in the base defense. Grade: Average.

Josh Jones, S, second round: Like King, Jones has been solid but not spectacular. In his case, that might be a bigger surprise considering how much he was around the ball in the offseason practices. Still, he’s been a willing tackler and has played both safety and inside linebacker in the oft-used “nitro” defensive package. Grade: Average.

Montravius Adams, DT, third round: A training camp foot injury that required surgery slowed Adams’ development and he’s been used only sparingly in his return. The Packers haven’t needed much help from him given how much Mike Daniels and Kenny Clark have played up front. Grade: Below average.

Vince Biegel, OLB, fourth round: After passing on his Wisconsin teammate T.J. Watt in the draft, the Packers thought they were getting the next-best thing in Biegel. But a recurring foot injury that required a second surgery in less than a year put him on the PUP list to start the season and delayed any impact he might have on the Packers’ struggling pass rush. Grade: Incomplete.

Jamaal Williams, RB, fourth round: Early in training camp, Williams pushed Ty Montgomery for the starting running back spot. But after Montgomery held onto the job, Williams’ run as the No. 2 back didn’t last long. A knee injury in Week 4 after Montgomery dropped out with broken ribs ended his short run as the go-to back and started a free-fall down the depth chart. Grade: Below average.

DeAngelo Yancey, WR, fifth round: Cut at the end of the training camp, he was re-signed to the practice squad. Grade: Incomplete.

Aaron Jones, RB, fifth round: He didn’t get his first carry until after Montgomery and Williams were injured against the Bears on Sept. 28, but since then he’s been the No. 1 back. He posted a pair of 100-yard rushing games in a three-week stretch. He runs hard, makes quick cuts and looks like he should only get better with experience. So far, he's the star of this draft class. Grade: Near perfection.

Kofi Amichia, G/T, sixth round: Cut at the end of the training camp, he was re-signed to the practice squad. Grade: Incomplete.

Devante Mays, RB, seventh round: With Jones, Montgomery and Williams ahead of him, Mays has not played from scrimmage yet this season and has been active for just three games, playing only on special teams. Grade: Incomplete.

Malachi Dupre, WR, seventh round: Cut at the end of the training camp, Dupre was signed to the Buffalo Bills' practice squad. Grade: Incomplete.
