The Las Vegas Raiders' defense is a good bit away from being even an above-average unit in the NFL. Between losing both starting linebackers and all five starting defensive backs from last year's team, there are a lot of moving pieces for defensive coordinator Patrick Graham.
Maxx Crosby and the defensive line are expected to do great things this season, but they can only do so much with so many question marks behind them. While they should be able to patch things together with their veteran experience at linebacker, many think they need to fortify the secondary.
While there are a handful of options out there to patch things up, another school of thought would be to bolster what is already a strength.
