When Pete Carroll took over for the Las Vegas Raiders, he chose to retain defensive coordinator Patrick Graham. Not only was this one less new coach for the fan base to learn during yet another regime change, but it seemed to mean that a lot of Raiders defenders would stay in Las Vegas.
Unfortunately, that theory was proven incorrect quite quickly, as the Raiders had a defensive overhaul this offseason. The defensive line stayed intact, but both starting linebackers and all five starting defensive backs from last season were released, traded or not re-signed in free agency.
Among the depth pieces that remained in the secondary were Isaiah Pola-Mao, who has become a starter at safety, Kyu Blu Kelly, who started at cornerback until his Week 14 injury, Decamerion Richardson, who has not seen the field on defense, and Darnay Holmes, who has been up-and-down.
