Lets look a little deeper last year/this year. The perception of a different balance of offensive result may be mostly just that ... a perception.
Through 3 games 2012: N.Texas, Washington, Idaho
.....Run yds r/TD
LSU 137 798 12
Opp 85 141 0
.....C-At-INT yds p/TD
LSU 48-68-2 709 4
Opp 49-93-5 476 4
Through 3 games 2013: TCU, UAB, Kent State
Rushing Runs yds TDs

Opp 101 332 4
Passing: C A Int Yds TDs
LSU 46-70-0 808 9
Opp 44-82-1 471 1
This year, we are scoring more TDs passing, but are not as much scoring rushing the ball. Overall offensive production is about the same, yardage, TDs, etc. Our running game is statistically not as productive, but we are slightly improved in offensive pass production, slightly lower percent completions but fewer ints, etc.
On the other hand, we have fewer interceptions on defense, and are allowing more rushing TDs, more rushing yardage etc.
Summary: I'm not seeing much offensive difference 2012-2013, at least in the cumulative. But I think the timing of passing/running plays may be different so that it appears the offense itself is different.
I do think there is a slight statistical decline in the defense, and possibly in the running attack, but that may be because of a change in pattern, not frequency, of play calling.
