Volunteers vs Crimson Tide coverage

Watching the Alabama-Tennessee game again, I noticed an interesting formation in the third quarter (maybe they did it earlier, I don't recall).
You may remember the drive. It was 20-6 and Eddie Lacy had 2 good back-to-back runs.

Formation:

Darius Hanks split out, off the line

Brad Smelley in the slot
  Michael Williams on the end
  Chance Warmack LG
  William Vlachos at Center
  Alfred McCullough RG
  DJ Fluker RT
  Barrett Jones at end

  Marquis Maze split out, on the line

Basically, it's moving Barrett Jones from LT to the other side of RT and they ran it down the Vols' throat.

In this formation, Lacy ran for 13 yards and then 16 followed by Trent Richardson for 16 to the 3 yd line.
Next play got them to the 1 but Vlachos was caught holding and pushed them back to the 13.
The next play was back to a normal formation but it was awesome to see the Tide just run at will.
(Trent scored two plays later).
