Since we're playing TCU and we already ran them by 29 at their place, I would put Harris into the line up, take Braun out and slide Garrett to the 2 spot.
McCormack had arguably his best game of the season against TCU so unless he's one of the guys Self said didn't respond well in practice yesterday, I'd keep him in the starting line up at least for Thursday.
I still think as long as Self is going to play through the post with roster instead of basing the on motion, pick and roll, screen and roll and other action to open up driving lanes, the offense is going to struggle with consistency.
