So much has been made about the Las Vegas Raiders' roster turnover this offseason. New general manager John Spytek and head coach Pete Carroll certainly revitalized the offensive side of the ball, but they left several question marks on defense that have still not been answered.
Not a single starter from last year's secondary or linebacker room remains on the roster in Las Vegas, so it has been a complete overhaul. While the linebacker corps is equipped with several savvy veterans, the secondary is devoid of an experienced leader.
The cornerback room is in a bit of peril just weeks before the season, but the safety room could also use an upgrade.
