Personally, I'd give White and Caldwell both a shot at earning a spot. Obviously one of them will be stepping in for the injured Brisiel. Give the other a shot at C.
I just find it hard to believe that Myers is the best option we've got. It surely doesn't say much for Caldwell and White.
I wanted to agree with DaleMurphy in the other thread about putting Butler at RT; but on second thought, after reading your post, I just thought perhaps it's not a good idea to have too many different guys and/or changing the line-up too drastically at this point in the season.
It's better we stay put as much as possible with what we have.
Brown, Myers, and Winston at their usual spot.
Have two guys (Studdard/White/Caldwell) at the two Guard spots, and use the third guy to rotate to keep them fresh.
