EDGE Analysis

Following the free-agent departure of Josh Jacobs, White heads into the coming season as the team's presumed lead back, while Mattison is line to work behind him in a complementary role that would set up the former Viking to be next up for added carries should White suffer an injury. Meanwhile, as the Raiders' second preseason game approaches, Reed indicates that Ameer Abdullah and rookie Dylan Laube are still competing to see who secures Las Vegas' primary third-down RB duties.
