they probably didn't emphasize it because...
LSU has out gained its opponents 2584 - 1763, as opposed to ksu being out gained by its opponents 2017 - 2074*.
Further LSU has outscored its oppy's 269-67, as opposed to KSU who has outscored its oppy's 176 - 117.
Against Ranked Opponents (LSU has played 4 top 25 teams this season), LSU has out gained its opponents 1453 - 1274, while outscoring them 147-50.
Against our 4 biggest opponents (Miami, Baylor (15), Mizzou, and Tech) we have been out gained 1379 - 1746*, while only outscoring them 129 - 110.
Its nice to pick out one game and be all like "HAI MAN, WHATS BOUT THAT WVU GAME?!!!?!?!?!!

"
but looking at the story of the season and the consistency that LSU has maintained vs what can only be described as "Schemeyness" by the @UATz may give you a little bit of a reason why the media emphasizes those numbers.
