Jamal Agnew, NFL's leading punt returner, highlights Lions' rookie class

Here’s a look at how the Detroit Lions rookies have fared during the first half of the season:

Jarrad Davis, LB, first round: He’s started at middle linebacker since he arrived in Michigan and handled things well for a rookie. There have been mistakes here and there, but he’s been strong in run coverage. Pass coverage is still an issue, but he’s adjusted fairly well overall -- particularly after missing two games due to injury. Grade: Above Average.

Teez Tabor, CB, second round: Tabor has been inactive almost every game this season and has played a handful of defensive snaps. He was never expected to have much of a 2017 contribution and right now, the Lions have to hope he takes a big leap in 2018, when he might be counted on to contribute. Grade: Bring on 2018.

Kenny Golladay, WR, third round: He had a hot start with two touchdowns in the season opener. After that, though, he’s been mostly unavailable, missing the entire month of October with a hamstring injury. The potential is there but not enough play exists to make an evaluation. Grade: Incomplete.

Jalen Reeves-Maybin, LB, fourth round: After mostly being a special-teams player, he got a good run as the No. 3 linebacker against Pittsburgh and showed strong potential. He had nine tackles combined in losses to New Orleans and Pittsburgh and his speed is something Detroit had been missing in its linebacker corps. Grade: Average.

Michael Roberts, TE, fourth round: Like Tabor, not much was expected from him as a rookie. He had two veterans in front of him but has slowly started to get more opportunities. Drops have come up here and there, but unless there’s an injury, he’s doing pretty much what’s expected this season. Grade: Bring on 2018.

Jamal Agnew, CB/Returner, fifth round: He was unlikely to see the field in a deep secondary room, but he’s been a revelation at returner for Detroit with two punt returns for touchdowns. He leads the league in average punt return (21.69) by over seven yards and is the only player in the league with multiple punt returns for touchdowns. Grade: Near perfection.

Jeremiah Ledbetter, DT, sixth round: He ended up making the roster and is a rotational defensive tackle. He hasn’t gotten a ton of work and has seven tackles. Grade: Bring on 2018.

Brad Kaaya, QB, sixth round: He was released during final roster cuts, signed with Carolina and then ended up back on Detroit’s practice squad. This is a long-term play. Grade: Bring on 2018.

Pat O’Connor, DE, seventh round: He was cut by the Lions and landed on Tampa Bay’s practice squad. Grade: Below average.

Jeremiah Valoaga, DE, undrafted: He made the team out of camp and has been a decent rotational end for the Lions with four tackles and a sack. He could be a breakout player in the future, though. Grade: Bring on 2018.

Tion Green, RB, undrafted: Green made the Lions based off a strong preseason, but has yet to be active for a game. If Detroit’s running backs still struggle, it could be interesting to see if the Lions eventually put him in the mix. Until then, he is a longer-term project. Grade: Bring on 2018.
