The LSU Tigers defense took a major step backward last weekend and will be tested again against the Texas A&M Aggies, which boasts the best slate of athletes the Tigers have seen this season.

LSU's vaunted secondary was able to slow down the Vanderbilt Commodores' passing game last week, allowing just 51 yards outside of the numbers.

It didn't matter, though, because they couldn't keep up with anyone in space. Both the between the numbers passing, 10-of-11 for 109 yards, and rushing attack dominated. 

Harold Perkins was playing out of position and wasn't able to adjust. LSU as a whole had 12 missed tackles. Six of those were from PJ Woodland and A.J. Haulcy.

The middle of the field was a nightmare for the Tigers and that is where a large bulk of the Aggies' passing offense comes from.

Marcel Reed is 77-of-118 for 1,095 yards with six touchdowns and two interceptions when passing between the numbers this season.

Reed has elite athletes to work with, which could become an issue if LSU cannot adjust to what killed them last week.

There are four names that the Tigers will need to focus on slowing down, outside of Reed. Reuben Owens and Le'Veon Moss are both nearing 400 yards on the ground. Mario Craver and Kevin Concepcion would both lead LSU in receiving by nearly 500 yards, with the former leading all SEC receivers with 674 yards.

Starting with the rushing attack, Texas A&M ranks No. 30 nationally with 196.7 rushing yards per game. Just around 16 yards less than the Commodores, who finished with 239 yards and three touchdowns.

Owens has 296 yards and three scores this season. He's forced 235 of those came after contact and he's forced 10 missed tackles. He is 5-foot-11, 216-pounds and quick-footed. He's also the best pass-catching back on the roster.

Moss has 389 yards and six touchdowns. He was a track star in high school and will punish the defense if they let him get to the second level.

Then there's Reed, who had his breakout game on the ground last year against the Tigers. Perkins must spy him more, which is harder to do without Whit Weeks.

If LSU can step up in the run game, then they will have the receivers to worry about.

Craver is the one to watch, as he has dominated the middle of the field this season working out of the slot. He has 31 catches on 39 targets for 551 yards between the numbers this season.

The Tigers are going to have to be much better against the things that lost them the game last week. This late in the season, adjustments are harder to come by, but something will have to change.
