As LSU prepares to begin spring practice March 14, GeauxTigerNation will take daily looks at aspects of the spring camp. This is the sixth in the series:
BATON ROUGE, La. -- In four years, LSU defensive coordinator John Chavis has not yet had a unit allow an average of 20 points per game. No defense has allowed more than than an average 328 yards a game, not more than 307 yards an outing after his first season.
Can he maintain that kind of quality?
Maybe, but if he does, it will be through perhaps his best rebuilding job to date at LSU, one that starts this week when the Tigers begin spring practice.
LSU returns starters at just four positions on defense and enters spring trying to revamp a defensive line that lost all four of its starters and six of its top nine players.
On paper, one might argue that it's the biggest challenge yet for Chavis at LSU.
One might disagree at first blush. When Chavis arrived in 2009, he was replacing Bradley Dale Peveto and Doug Mallory after the Tigers were perceived to have given up too many points and too many big plays in an 8-5 season. Many looked at the departures as a purging, of sorts, of the defensive problems.
But looking back, that 2008 defense only allowed a reasonable 325 yards per game and 24 points per gam, and those totals were skewed by an offense that committed 20 turnovers, often leading to points for the opposition. That 2009 defense returned six starters, including four future NFL draft picks.
Chavis' first defense actually gave up more yards per game (just under 329) than the 2008 team, but allowed a touchdown a game fewer thanks in no small part to the elimination of big plays by the defense and turnovers on offense.
So this year's defense will have to replace more starters and have to live up to a greater expectation.
After his first year, Chavis' teams have been allowing at least 20 yards less per game than that first defense.
Three things will have to happen if LSU is going to continue its dominance under Chavis. LSU must:
Find playmakers on the defensive line. With all four starters gone, the Tigers will need a leader -- perhaps big-play tackle Anthony Johnson -- and some young talent to emerge. LSU has recruited well on the defensive line, but the talent is unproven. Young defensive linemen will have to make names for themselves this spring.
Find a middle linebacker. With Kevin Minter's departure to the NFL, the Tigers don't have an obvious choice to lead the defense from the middle linebacker spot. Lamin Barrow was a 100-tackle star on the weak side, but does his game fit that of a middle linebacker? If not, which of LSU's many young prospects will step up in Minter's spot?
Find a leader in the secondary. Eric Reid was a solid player, a good student and a natural leader at free safety. With Reid also in the NFL, does LSU have a leader in the secondary? Reid, Tyrann Mathieu, Morris Claiborne and Patrick Peterson are among the players LSU has had in the defensive backfield who came with leadership qualities. Can LSU can that from Craig Loston or one of the Jalens (Mills or Collins) at cornerback? How about from a new starter, potentially Ronald Martin?
