That's what it probably is, at present. I also agree with your comments. Teague at LT would be my only concern. Losman does like to roll to the right side, which can only help. Plus he can actually sense a pass rush.
My thought is stick Peters next to Mike Williams as a TE/Tackle eligible. Run and run some more. Don't forget Shelton/Lawton as good blocking FB's , leading the way.
