The Raiders led the league last season when they allowed 38 passing plays of 25 yards or more.
Considering the investments tied up in their secondary, that was beyond unacceptable. It cost defensive backs coach Marcus Robertson his job and has general manager Reggie McKenzie and coach Jack Del Rio spending the offseason looking for ways to improve.
Barring a surprising decision to move on from cornerbacks Sean Smith and David Amerson — both of whom have lucrative deals that become fully guaranteed for 2017 on March 11 — the Raiders will have the same two starting cornerbacks.
