It appears as if head coach Mike McCarthy and the Packers will be rotating Barbre and Daryn Colledge until they settle on a starter just like they did at minicamp and OTA practices.
The Packers certainly could make a decision at any time, but you'd think that they'll be rotating at least through the first two preseason games perhaps giving each one of them a start with the first team.
By that time, they probably should pick a starter and go with it. They're probably not going to see a whole lot more from either Colledge or Barbre in the final two preseason games than they saw in the first two or the Family Night scrimmage. Or their professional careers for that matter.
