Les Miles has had a whole lot of success at LSU. He has a national championship, along with two SEC championships. He’s made a bowl game in each of his 10 seasons and won more than 100 games in that span.

He’s sent dozens of players to the NFL; LSU had more players on NFL rosters at the start of last season than any school in the nation.

Miles has done exceedingly well in recruiting as well, with eight classes ranked in the top 10 in his 11 recruiting cycles.

Those last two notes come with a caveat, though: the quarterbacks. Miles has recruited several elite high school quarterbacks, guys like Russell Shepard and Ryan Perriloux were five-stars coming into college, and many other three- and four-star players dot his list of signees. In 10 years, though, Miles has only seen three of his quarterbacks head to the pros. Two of them, Matt Flynn and JaMarcus Russell, weren’t his recruits, though. Zach Mettenberger, a junior college transfer, is the only Miles recruit to make it to the NFL.

LSU is a hotbed for just about every position. Wide receivers, defensive linemen, running backs and defensive backs from the school fill NFL rosters every year. Yet quarterback has not been a place where LSU has been able to both recruit and develop elite-level talent.

Part of the problem is LSU’s recruiting territory. The Tigers own Louisiana, and every year bring in a huge haul of recruits from their home state. Just three times since Miles took over in 2005 has one of the top-10 recruits in the state been a quarterback. LSU landed all three: Ryan Perriloux, Jordan Jefferson and Brandon Harris; Perriloux didn’t work out either on or off the field, Jefferson did not live up to expectations and the jury is still out on Harris.

The Tigers did develop Flynn and Mettenberger under Miles’ watch, but there have been failures as well. Perriloux stands as the biggest whiff, while Shepard was moved to receiver by the end of his career. Stephen Rivers, Chris Garrett and Jerrard Russell all transferred out, Jefferson and Jarrett Lee didn’t amount to their potential. Zach Lee had potential, but picked a signing bonus of more than $5 million from MLB’s Los Angeles Dodgers over college football.

Quarterback, and whether or not the passers on the roster now can win, is one of the biggest questions facing the current iteration of LSU football. Offensive coordinator Cam Cameron’s offensive philosophy favors drop-back passers with big arms. While Harris fits the big arm criteria, neither he nor Anthony Jennings is a three-step drop expert. According to a report from ESPN’s Jeremy Crabtree, LSU is moving away from that when recruiting passers.

“There’s definitely an element of change to what we’re looking for in recruiting now. We need a guy that has an ability to not necessarily be a dual-threat guy, but a guy that can extend the plays. Those are key words — the ability to extend the play,” LSU player personnel director Austin Thomas told Crabtree.

“First and foremost you have to have a decision-maker,” Miles added. “Whether it’s a guy that can read a defensive end and know to disconnect or give, or read a secondary and make the right throw. He has to be a great decision-maker first.”

The Tigers are heading that direction. Their biggest commitment so far for the 2016 class is Feleipe Franks, the top rated dual-threat quarterback in the country. He’s big, at 6-foot-6, and can use his athleticism to give himself room to throw. With the offensive wrinkles Cameron began to unveil at the tail end of last season, Franks could be the ideal fit for a new mold of quarterback at LSU.

Before Franks arrives, the hope is that Harris (or Jennings) can break LSU’s lack of success at quarterback. While he’s not a major physical specimen, listed last season at 6-foot-3 and 188 pounds, Harris has the athleticism and arm strength to fill what the Tigers sound like they’re looking for. And if he’s been in the playbook and Cameron’s offense the way he says he was all spring, he could check the decision-making box as well.

Miles is undoubtedly one of, if not the best coach in LSU history. If he can begin to repair his track record with quarterbacks, LSU can vault right back to national contender status while leaving critics very little to pick at.
