With the drafting of Chris Williams with the Bears first pick it has been assumed that incumbent left tackle, John Tait, would move to the right side and let Williams, considered the only true left tackle in the draft, take over that spot, but nothing was official.
While it still isn't at camp John Tait ran reps with the first team at the right side with John St. Clair working on the left side.
Both moves make sense. Get Tait as many reps at right and St. Clair practices at left in case Williams is a hold out or isn't ready to take over the position.
