The Oakland Raiders have bolstered their defensive line heading into the weekend with the news that they've signed former New York Giant Dave Tollefson. It's a move every team in the AFC West is trying to make, and Tollefson is a solid signing for a defensive unit that will look to mold itself in Dennis Allen's image.

Steve Corkran writes, "Tollefson started two games last season and posted a career-high five sacks. His signing will help offset the loss of veteran defensive linemen Jarvis Moss and Trevor Scott. Moss remains a free agent. Scott signed with the New England Patriots earlier in free agency. The Raiders won't comment on the matter until the contract is signed and the league approves the paperwork."

Mike Florio notes that it's likely the Raiders will run at 4-3 defense which, he writes, means Tollefson will serve as a defensive end for the team. He'll be a nice rotational player to help the Raiders in a number of ways.
