Winchester and Myres started against Arizona, but Johnson and Winchester saw the most plays. Myres was in there quite a bit as well and Arizona tended to only attack Johnson out of those 3. Basically, we have 3 CBs that rotate often.
As far as Wooten, unless a guy is a stud OL out of high school, most really won't play until they become a junior/senior. Most need to build strength and technique for 2-3 years before being effective.
