Either GBPG or JSO. They mentioned that he beat Peppers twice at his regular RT position, and Matthews once while lining up as a LT. I read a bunch of different articles, but I will see if I can find it. I found it especially noteworthy that Bulaga was taking reps there this early, which indicates that Sherrod might not be solidly in their plans so that Bulaga would have to be the backup on the left, or that they want to do everything to be better than Bakhtiari was last year, either with an improved Bakhtiari or with the 2013 plan of Bulaga on the left.
Remember these are just 1-on-1s and I thought I read that they wanted him to go against Clay in the first matchup. Clay rushes from that side so he probably just adjusted his stance and footwork and they went at it. Then back to the right side. Maybe there's more to it, but I personally wouldn't read anything about Sherrod into it at this point.

http://www.packersnews.com/story/spo...gles/13299123/■ Bulaga had a strong day in one-on-one drills, winning a battle against Clay Matthews while lining up at left tackle and then holding his own against Julius Peppers twice from his usual post at right tackle.
