Wide receiver and linebacker are the Raiders' two biggest needs as they enter the offseason.
But the Silver and Black need upgrades across the entire defense. All eleven positions will be evaluated and improved if possible. That improvement won't just be for the starting unit, but for the depth as well.
While the linebackers are the most glaring issue, the secondary also needs to be fixed. Trayvon Mullen showed lock-down potential during his rookie season, and the Raiders will be excited to get Johnathan Abram on the field in 2020.
The Raiders first can address their leaky defense in free agency, before turning their attention to the 2020 NFL Draft.
