It makes absolutely no sense to redshirt KB if TL takes over the starting position. If that were to happen and TL gets hurt, this season goes to heck. CB is a good athlete and will develop but he is not ready for the #2 spot.
Of course we need him, and I think he wants to end his career in Clemson, but in the end, the choice is his to make and he's earned that right. I think at this point he will do what is best for the team.
