Overview
LSU’s DC is Dave Aranda, one of the best in the SEC and compensated accordingly. He is literally from the same school as Todd Orlando – preceding Orlando as DC of Utah State and recommending him as successor. Aranda instills a similar aggression in his defense, causing many negative plays but they do also give up some big plays as a result of taking risks. His defenses are very sound against the run and cover well. Playing in the SEC he hasn’t developed the level of disguise and chaos looks that Orlando has at Texas but the defense is strong and it’s the calling card at LSU.
The LSU defense is a base 3-4 which uses the safeties aggressively as robbers but I suspect they will be forced into 3-3 nickel against Texas. They even have a 2-4-5 nickel scheme which is basically a 4-2-5 with both OLBs functioning as standup DEs but that is a 3rd and long special. LSU is smaller than Georgia but both quicker and more disruptive on defense. In 2018 they recorded 34 sacks and 83 TFLs. They penetrate and take risks so they both give up more big plays while creating more negative plays for the offense. The result is an above average run defense (#41 at 3.9 YPC) but with the ability to terminate drives regularly with a negative play. The 2018 pass defense was excellent - #4 in pass efficiency defense is good even if that was against the SEC. 65 PBUs and 17 interceptions are good numbers against anyone. They lose their leading pass rusher and DB but return 7 so I expect them to still be good.
Pass Defense
Aranda runs 2 basic coverage schemes: a match quarters semi-zone called Tite 4 and man-free called Under 1. The interesting feature is that the CBs are nearly always in man coverage on the outside and are often pressing at the LOS. In match quarters, the safeties are back in cover 2, 2 LBs (an OLB on one side and an ILB on the other) cover the flats while the corners man up from 7-10 yards off the ball. UGa gave their LBs similar responsibility for coverage in the flats and they still can’t get the bad taste out of their mouths. It’s basically a 2-deep, 3 under zone inside with man coverage on the outside. There is going to be a lot of space between the underneath defenders if the CBs get run off deep.
Man free drops one of the safeties down over the slot and the other plays center field while the LBs have man responsibility for the RB to their side of the field. That matchup outside isn’t going to be good for LSU but CBs near the LOS in press coverage will allow them to come up quicker in support against the run or quick swing / flare to the RBs. To me this scheme relies too much on the ability of the individual DBs to make a play but since they usually have a talent advantage it works for them most of the time.
LSU’s pass rush generally brings 4, with a different LB providing the 4th man each time. They create a good amount of pressure In their base package. You will see a lot of simulated pressures with 6-7 defenders near the LOS but only 3-4 rushing, very similar to what Orlando does in that regard. Aranda doesn’t blitz that often but he has some effective ones when he brings it, particularly from DBs lined up with inside leverage over the slot. That’s where they tend to give up big plays but also create sacks and turnovers. We may see Aranda take more risks in Austin, especially if LSU’s offense continues to sputter and they need the defense to help them score. Those are very much the exception however. Their DC prefers disguised 4 man pressures like fire zone concepts from a heavy blitz pre-snap look. It won’t be as innovative as what we see from Orlando, Patterson and Campbell because Aranda hasn’t faced the Darwinian pressure to survive against multiple Air Raid and Spread offenses every year. Expect it to be effective creating pressure anyway – especially with athletes better than those available to any of those coaches other than Todd Orlando. Disguising the pass rush is where Aranda does the best job of creating uncertainty for the offense.
