When ranking the positions at LSU, it’s pretty obvious where LSU’s strength is.

Just look at the cover of this year’s football magazines and the answer will stare you in the face.

But where’s its weakness?

We all know about LSU’s famous lack of a passing game for most of Les Miles’ tenure, but there’s a part of the Tigers’ defense that may be considered even weaker this year.

Here are the position groups at LSU, ranked strongest to weakest:

Running back

LSU may like to call itself “DBU,” but it’s quickly becoming “RBU.”

With NFL stars like Jeremy Hill and Alfred Blue having come out of the program, and Heisman Trophy candidate Leonard Fournette spearheading a deep stable now, the position is an accumulation of talent that Miles and his staff didn’t have to go far to find.

Fournette, who rushed for 1,953 yards last season, is from New Orleans and the four backs behind him all hail from Louisiana, within an hour of LSU’s campus. That includes Derrius Guice, the talented rising sophomore backup from Baton Rouge.

Who can blame Miles for favoring an old-school, Big Ten power football approach when his recruiting base keeps giving him players like this?

At fullback, junior John David Moore was a great blocker when he was healthy and Bry’Kiethon Mouton was a good lead blocker with ball skills. The Tigers aren’t great there, but solid.

Secondary

When you count recruiting stars, LSU’s “DBU” title applies here. With former elite recruits like Tre’Davious White, Kevin Toliver and true freshman Kristian Fulton in the fold, LSU is loaded with top-end talent.

It didn’t add up to results last year as the Tigers were 12th in the SEC in pass defense. But with all of the key players except Jalen Mills back, this group has a chance to be special.

Both White and safety Jamal Adams are potential first-round draft picks in the 2017 draft, and Toliver has the ability to be a high pick for years to come. And with Fulton and talented Saivion Smith joining the group, the elite-level talent remains plentiful.

Defensive line

Both lines have strengths and weaknesses, but the defensive side gets the slight edge because it has everybody back even if they may not be settled in their roles yet, and it’s unclear how well they’ll fit those roles as LSU shifts from a 4-3 base to a 3-4 under new defensive coordintor Dave Aranda.

Defensive tackles Davon Godchaux and Christian LaCouture are back, but Godchaux is now a nose tackle and LaCouture a defensive end. Ends Arden Key and Lewis Neal are back, but Key is playing a hybrid linebacker/defensive end position.

All four were at least pretty good in their roles last year, it’s just that those roles are now being redefined. Defensive line coach Ed Orgeron has to find the right combination in a new scheme.

Offensive line

There’s talent here as LSU has three returning starters, including one of the nation’s best centers in senior Ethan Pocic and a rising star in Maea Teuhema, who started 11 games at guard as a true freshman.

But the Tigers also lost two starting tackles and a position shuffle to replace them has left some question marks. Teuhema was moved from guard to left tackle in the spring, but it’s not clear whether that’s his best position.

Toby Weathersby and K.J. Malone are competing for the right tackle spots. Meanwhile, Teuhema’s move to tackle would leave offensive line coach Jeff Grimes searching for a new starter at guard as well (likely senior Josh Boutte).

With its power running game, LSU has no problem finding talented big men willing to play smash-mouth football, even if Louisiana isn’t as good at producing talent at this position as it is others (Teuhema, Pocic and Weathersby are all out-of-state recruiting wins). So this is a strong position, just one with question marks.

Wide receivers/tight ends

The good news is LSU has its leading receivers from the last two seasons still on the roster. Junior Malachi Dupre led the team in 2015 and senior Travin Dural was the leading receiver in 2014. More good news is that LSU is typically able to land first-rate recruits like Dupre and sophomore Tyron Johnson without having to leave the state.

But this group won’t be ranked higher until LSU’s anemic passing game improves. Dupre and Dural likely have NFL futures, but both could be more consistent. Behind them, LSU doesn’t have a proven, consistent producer.

At tight end, returning starter Colin Jeter is the most versatile player in a group that includes a blocking specialist in Foster Moreau and a pass-catching specialist in DeSean Smith. It remains a position under-utilized in LSU’s offense.

Quarterback

As LSU has gained a reputation for being a run-first program, the school has had trouble attracting high-end quarterback prospects.

Brandon Harris, the returning starter, was one coming out of high school, an Elite 11 participant and the nation’s No. 2-rated dual-threat QB in the 2014 recruiting cycle. However, his numbers need to improve before this position can be considered a strength. He passed for 2,165 yards and a modest 13 touchdowns as a sophomore.

Behind him, LSU has a Purdue cast-off in junior Danny Etling and a couple of former three-star high school recruits in Justin McMillan and Lindsey Scott Jr.

There definitely is not the talent accumulation here that LSU sees at most positions, and Harris must prove himself both for the Tigers’ immediate future and to show that LSU can, indeed, develop quarterbacks.

Linebacker

With 2015 tackles leader Deion Jones having moved on to the NFL and Lamar Louis departed after his senior season, LSU can be thankful Kendell Beckwith returned for his senior season to anchor the group.

Around him, Beckwith is surrounded by unproven players. Duke Riley has been good at special teams, but the senior slated to start next to Beckwith has played little in games at his position.

Meanwhile, the outside linebacker spots are a hodge-podge of former defensive linemen (see Key and former defensive end Tashawn Bower) and defensive backs (see Corey Thompson) learning new spots.

Beckwith is a pretty good start, but this group is otherwise full of question marks. If Key proves to be a natural at his position and Riley pans out, it could end up being a strength.

But until then, it’s the thinnest and most worrisome group in the program.
