Here's a look at the first-half impact of the Oakland Raiders' draft class:
Gareon Conley, CB, first round: Having fallen to the Raiders at No. 24 overall after being accused of sexual assault -- a grand jury declined to pursue charges -- Conley has dealt with an injured right shin that wiped out training camp and preseason. He has appeared in only two games and is not expected to make another run at playing until after the bye. Grade: Incomplete.
Obi Melifonwu, S, second round: Unlike with Conley, the Raiders literally got nothing from Melifonwu in the first half of the season, as he was on injured reserve after suffering a knee injury in training camp.
