As is becoming the custom around the league, the Raiders have their entire draft class signed well before training camp.

Oakland reached a four-year pact with guard Gabe Jackson on Thursday, the club said. He is the eighth and final of the Raiders’ selections to reach a deal.

A third-round pick, the 6-foot-3, 336-pound Jackson was a four-year starter at Mississippi State. He’s a youthful addition to a guard depth chart that has been revamped, with ex-Jet Austin Howard and ex-Giant Kevin Boothe among the new options inside in Oakland.

“He’s a powerful, physical young man. When you’re building a guard, physically, that’s what they look like,” Raiders director of player personnel Joey Clinkscales said of Jackson after the draft, according to the club’s website.
