Position switch for Levi Brown?

One of the major malfunctions of the Arizona Cardinals' offense in 2012 was the lack of protection the offensive line afforded the gentlemen that occupied the QB position. A big part of that malfunction was the fact that starting LT Levi Brown missed the entire season with a tear to his triceps muscle. In any event, Brown appears to be ready to roll again for 2013, but there is some speculation that he could be moved inside to guard, depending upon who is brought in via free agency and the draft.
