Do you have a gif of this play? A still picture doesn't tell the whole story. This picture looks to me like he is looking back to hear the QB or see if he is motioning. Linemen do that all the time.

LG pulls and gets handed his lunch. Everyone on the D knows he's the pulling man because he is a half yard behind everyone else. Gotta get his ass on the LOS to help keep the play disguised. You run plays like you practice them.
Edit: https://vine.co/v/eYe79VEqzdQ Here is another example. whole point is that you can't telegraph the fact your the pulling blocker. If the starter doesn't execute it, pull them for someone else. Still a coaching decision.
Those 2 plays make Lowry out to be Reggie White.
On #1, that should never happen to a pulling guard. NEVER! Utter should have some speed built up, but he gets knocked on his ass by Lowry.
On #2, Sterup gets pancaked by Lowry. Wow.
good god those are bad
