Interesting perceptions vs. reality regarding the Miles and Orgeron offenses

Total yards, yards per play, and scoring offense are hugely in favor of Orgeron so far in 2016. However, reading other threads it I find it interesting how perception has become reality with respect to HOW LSU is getting to those numbers.

I've seen people suggest it is the result of significantly more plays, yet LSU is averaging less than 4 plays more with Orgeron than they did with Miles - hardly a noticeable number over the course of a game.

Others have suggested it is more passing plays - LSU is averaging less than half an attempt more with Orgeron than Miles. In fact, LSU is actually passing the ball 40.4% of the time with Orgeron and passed it 41.9% of the time with Miles.

This offense is still as run oriented as ever. The biggest change in personnel groupings has been that Orgeron uses the single-back, double TE set much more frequently than Les did. Orgeron also, and surprisingly, uses the 3 WR, 1 TE, 1 RB set much less frequently than Les did. The lauded 4 WR set was used early but is statistically insignificant at this point.

Even if you get down to situational play calling, the numbers aren't nearly as different as they feel. Orgeron runs the ball on 62% of first downs. Miles ran it on 66% of first downs.

Granted, the defenses we've played in the last 3 games aren't as good as the group from the first 4, but that doesn't explain ALL of the massive improvements in total yards, yards per play, and points. However, when you dig into the more advanced stats the numbers aren't all that different, even though it feels much different when watching the game. We line up in double TE sets more now than ever. We used 3+ WRs more with Les than we've done with Orgeron. Where are the tangible, significant differences in the two systems? I know Orgeron can't exactly overhaul the entire offensive side of the ball, but are all the impressive numbers really the result of such relatively minor tweaks?
