With training camps opening, I thought I'd start a running thread of white vs black battles for starting positions. In Dallas, Doug Free vs Alex Barron for tackle. In San Diego, Brandon Dombrozski (spelling) vs a sumo for tackle. In San Francisco, will at least three whites start on O-line? In Philadelphia Mcglynn vs two sumos for starting center (I fear we will lose this one). In Jacksonville will Justin Smiley join Britton and Meester as third starting O-lineman.
