The Raiders biggest needs right now are defensive tackle and linebacker. They have just made a move to try and shore of one of those positions today with the signing of defensive tackle, Pat Sims.

Per Jason Garrison of Bengals blog, Cincy Jungle:

Sims was a third-round pick for the Bengals out of Auburn in 2008 and he has made his name as a solid run defender. Sims stands at 6-foot-2 and weighs in at 335 pounds and is like a brick wall when it comes to plugging holes on the defensive line. Unfortunately, he has had several injury issues in the past. He missed eight of the team's 16 games in 2012, five in 2011 and five more in 2008. The only complete season he played in was 2009. In his five seasons with the Bengals, he has made 138 tackles, five sacks and one interception. Sims, when healthy, has been a major part of Mike Zimmer's defense as he is likely the team's best run defender on the defensive line.

Sims' career starts came earlier in his career. He has never been the fulltime starter for the Bengals since being chosen as a third round pick out of Auburn. He started 22 games over his first three seasons but has started just one game over the last two. The 6-4, 312 pound defensive tackle has 5.0 career sacks. He had 36 combined tackles as a rookie and has seen his numbers steadily decline every season since.

The Raiders are the right team for him to try and get his career on track. Sims is expected to compete at the nose tackle/0 tech DT position. With the departures of Desmond Bryant and Richard Seymour along with the expected departure of Tommy Kelly, Sims will have a great shot at starting.
