Perhaps the Raiders allowed Tom Cable to steal Zach Miller because they had so many offensive line spots to fill.
Oakland confirmed the signings of four offensive linemen, including a surprise return of center Samson Satele. Also joining the fold: tackle Stephon Heyer, guard Justin Smiley and tackle Seth Wand.
Rookie Stefen Wisniewski is expected to start at center, but Satele gives the team options. Oakland needed more alternatives at tackle, where Heyer and Wand will provide depth.
We know our friend Mike Silver of Yahoo! Sports has already predicted the Raiders to the AFC Championship. It’s not that crazy a notion, but all the changes and random parts on their offensive line will be a big obstacle in their way.
