If the Raiders want to add a veteran defensive tackle, it will not be Grady Jackson. He signed with Atlanta on Monday night.
The Raiders had some interest in Jackson earlier this offseason. If Oakland is still interested in pursuing a veteran defensive tackle, the most recognizable name available is Sam Adams, who was on the Raiders' Super Bowl team in 2002.
At this point, though, Oakland may have to suffer an injury during training camp for it to make a move in the middle of its defensive line, especially with Tommy Kelly looking decent in his return from a torn ACL.
