JACKSONVILLE, Fla. -- Here’s a look at the first-half impact of the Jacksonville Jaguars' draft class:

Leonard Fournette, RB, first round: Fournette has been everything the Jaguars hoped he’d be. He rushed for 596 yards and scored at least one touchdown in the Jaguars’ first six games (he missed the seventh with an ankle injury and this past Sunday's game for a violation of a team rule). Fournette is the perfect fit for the style coach Doug Marrone wants to play. The biggest surprise has been his breakaway speed. Grade: Near perfection.

Cam Robinson, OT, second round: He has started at left tackle since opening day and has been the Jaguars’ best lineman. He gave up just one sack through the first seven games and has been good in the run game, too. He plays with an edge, which is something that had been missing from the Jaguars' offensive line. Grade: Near perfection.

Dawuane Smoot, DE, third round: It’s hard for him to get a lot of reps as a pass-rusher on a defensive line that features Calais Campbell, Dante Fowler Jr. and Yannick Ngakoue. Smoot has eight tackles and two quarterback hits, but most of his work has come on special teams. Grade: Below average.

Dede Westbrook, WR, fourth round: He missed the Jaguars’ first seven games as he recovered from core muscle surgery. The team eagerly awaited his return because he was pretty darn good in the preseason, leading all NFL receivers with 288 yards. Grade: Incomplete.

Blair Brown, LB, fifth round: Brown has played mainly special teams because it’s hard for him to get on the field over Paul Posluszny, Myles Jack and Telvin Smith. The Jaguars liked what he did in the preseason, especially how physical he was, but he’s at least a year away from being a heavy contributor on defense. Grade: Below average.

Jalen Myrick, CB, seventh round: He really struggled in training camp and it was a bit of a surprise he made the 53-man roster. Tom Coughlin said the Jaguars kept Myrick because of his speed, but he has been inactive for all but two games. His biggest contribution came against Cincinnati on Sunday, when he was forced into the nickel spot after Jalen Ramsey was ejected and did a solid job in coverage. Grade: Incomplete.

Marquez Williams, FB, seventh round: He was waived/injured on Sept. 1. Grade: Bring on 2018.
