There have been plenty of stories filled with the quotes all saying the same thing: Mettenberger will turn the corner as a quarterback because of new offensive coordinator Cam Cameron.
Yet few writers have actually said why or how. Instead, they just assume Cameron will make Mettenberger great.
In the words of Walter White, tread lightly, LSU fans.
People cite Cameron's amazing ability to develop quarterbacks. Yet few mention his best two, Drew Brees and Joe Flacco, became better quarterbacks when they moved on after Cameron.
But Mettenberger will only be with Cameron for a year. Flacco had a solid rookie season in his first year under Cameron's teaching. Flacco and Mettenberger are of similar build and skill set, which is a positive for LSU fans.
The problems facing the LSU passing attack from last year are still the same this year.
The Tigers are lacking a proven deep threat. Odell Beckham Jr. and Jarvis Landry are great receivers, but do not the fit the build of a guy who can scare defenses over the top. The loss of Rueben Randle to the NFL Draft severely hurt the offense in 2012.
LSU was the only school in the SEC to not have a receiver with a reception over 60 yards or have more than one receiver with a 50-yard reception. The Tigers put forth the effort to push the football down the field but could not ever connect.
Landry and Beckham will become more potent down-field. Travin Dural, Kadron Boone, Quantavius Leslie and others are candidates to make explosive plays. LSU also has better receiving tight ends to help Mettenberger attack the middle of the field.
Pass protection was an issue for LSU last season, too. The Tigers ranked 89th in the country in sacks allowed per game. Pass protection is still suspect, especially as the offensive line shifts bodies to cope with Williford's injury. But TCU will, more than likely, not have their best pass rusher in Fields.
TCU has a savvy secondary. Their best playmaker is Sam Carter, a safety who can do a little bit of everything. Kevin White and Jason Verrett are top-notch corners.
The best part of of Landry and Beckham's game is their crisp route-running. Yet the biggest challenge to those type of receivers are smart corners who work well with body leverage. Verrett and White both fit the mold.
The TCU secondary defended West Viriginia superbly last year. Tavon Austin and Stedman Bailey struggled because of the Horned Frogs' physicality. So the Horned Frogs are accustomed to stifling great receivers.
If LSU can run the ball, the passing game becomes easier. Yet there will be times where Mettenberger will need to fit the ball in tight windows.
Mettenberger eclipsed 200 yards passing in his last four regular season games. He will have some success, but will barely miss out on stretching the streak to five games.
