Without DE/DT Tommy Kelly, S Gibril Wilson, WR Javon Walker and OT Kwame Harris the Raiders were screwed for next year and wouldn't have enough pieces to even help their younger talent develop.
If you disregard these signings they had a multitude of problems and only 5 draft picks (no 3rd or 5th round picks) to fill them. This problems included, but weren't limited to:
- An extremely thin crop of talent along the offensive and defensive lines
- A paper thin WR corps with only one player who's had more then 6 catches in his career
- A huge need on the backside of their defense where they haven't had a pair of safeties who could both be possibly counted on in years
Even if all their signings work out they still need to find 2 more defensive ends (they have only 6 defensive linemen including 2 defensive ends in Derrick Burgess and Jay Richardson under contract) and another WR to even have the minimum number of players necessary to play next year. They also probably could use a backup QB, a upgrade at SLB, OC (they've got Jake Grove and no one else who could play the position), another offensive lineman (Paul McQuistan is their backup OG and is at best a journeyman OT and Mario Henderson has never played at the pro level before), etc.
It's hard to see what the Raiders are going to do next - because they're in tough and no one knows if the pockets of talent they've got will be undermined by the weaknesses at key spots. Here's hoping they get NY Giants lucky in the draft and hit on all their draft picks.
