They have two options:
First, move Kraemer to left guard and keep the right side intact with Mustipher, Bars, and Hainsey.
Or move Bars to left guard, Kraemer to right guard with Hainsey at right tackle.
As for left tackle, I think Eichenberg and Josh Lugg compete for the spot. There has been talk from the beat guys about how the good coaches think Josh Lugg is. They use words like "star". So we'll see on that.
