The Oakland Raiders, who have had an active offseason thus far, could be looking to add even more players.

Per Bill Williamson of ESPN.com, the Raiders want to add depth at defensive tackle.

To do so, they might pursue a couple of former Raiders — Sam Adams and Grady Jackson.

Jackson spent his first five NFL seasons with the Raiders, from 1997 through 2001, and Adams was a member of the 2002 edition of the team, which made it to the Super Bowl.
