With each passing day that the Bears do not address the tackle position with a free agent, it seems more likely G Chris Williams may move back to tackle, where he played his first two seasons. Citing an unnamed teammate, the Chicago Tribune reported Tuesday that Williams has worked out at tackle during the team's off-season workouts that are closed to the media and the public. Williams has started 16 games at tackle and 22 at guard in his career. The Bears had former Rams T Adam Goldberg in for a visit earlier in free agency, but never signed him.
