The Raiders are hunting for more pieces as they continue to build out their ascending roster.

With a functional offense featuring a promising quarterback, bulky offensive line and plenty of weapons, Oakland could stand to add some starting-caliber defenders.

They're reportedly looking at one in particularly, as they have a visit set up with USC hybrid defender Su'a Cravens, according to Sirius XM's Eddie Borsilli.

Cravens, 6-foot-1, 226 pounds, played three seasons at Southern California, racking up 207 career tackles, 34.5 tackles for loss, 10.5 sacks, nine interceptions, 16 batted passes, one fumble recovery and four forced fumbles.

The first-team All-Pac-12 selection moved around for the Trojans, playing linebacker and safety. Cravens fits the mold of versatile, multi-position players in the NFL like Arizona's Deone Bucannon and St. Louis' Mark Barron.
