When Richard Seymour and Tommy Kelly were told to leave Oakland, we knew that the defensive tackle position was going to be a problem. Reggie McKenzie signed Vance Walker and Pat Sims to be their "replacement", but we know that's not going happen. Vance Walker has a lot of talent, but Sims is a question mark.
When it was time for the Draft, everyone thought the Raiders were going to draft either Shariff Floyd or Star Lotulelei, but they ended up drafting a talent cornerback, DJ Hayden. The only defensive tackle they drafted was in the sixth round, Stacy McGee, and he probably won't fill in the hole either.
So why not give Sedrick Ellis a chance?
Ellis is proven to be a bust and never lived up to the 7th overall pick in the 2008 draft, but like Alex Barron, he can come in with a cheap and one year contract. If he impresses, he can start along side Walker. If he's okay, he can stay as a backup to Sims. If he's bad, he could be cut.
It's a win-win situation, Raiders gets a player with potential and Ellis gets a legitimate chance to start on a team.
