LSU's running game

Specifically with respect to the gashing runs that Scott had through what I think was the guard-center gap, has anyone looked at it enough to see which OL were doing the best work to spring Scott?

On a number of other plays, I was really impressed with Auburn's Senderrick (sp?) Marks, so I figure someone had to be blocking that beast effectively, but I could not tell if it was Helms, one of the guards, or double team blocks.

In any case, a great job.
