Hard to diagnose just looking at it like that.... Obviously LSU broke the one long run when I don't believe either LB was on the field, Wisc, we got manhandled at Oline, UVA I think their QB ran for a bunch of yards. Don't recall Duke or Vtech but I think giving up 110 yards TOTAL on the ground isn't awful. Not great like you said but def not in the realm of the others.
Not to mention when we look at Perine highlights he was running behind a completely different Oline with future NFL players. I think everyone, even the gator included, believe the Oline will have some drop-off so lets see how he does.
