Brad Biggs at the Chicago Tribune notes that guard Matt Slausongot work at back up center yesterday. It might be reading too much into it but the usual (and currently listed) back up, Edwin Williams has been having a quiet camp. Slauson played some center for the Jets.
Speakng of the depth chart, I thought it was notable that former number 8 overall pick with the Falcons, Jamaal Anderson, is last at defensive tackle. Looks like the Bears might not be getting much help there.
