re: 2nd Year O.C.'s Pattern?

All of the incoming OCs inherited a senior QB their first year.

Crowton came in for the 2007 season and had senior Matt Flynn. (Flynn should have been followed with Perrilloux, but instead was followed by Hatch, who was not experienced, and the freshmen JJ/JL... understandable drop off)

Studrawa was promoted to OC going into 2011 (I think); inherited two seniors: JL and JJ. His next year was Mett's first as starter. Mett had barely any playing experience with LSU... It is debatable whether the offense was better in 2011 or 2012. And for the last 2 or 3 games, 2011 offense was not good at all.

Cameron's first year, he gets Mettenberger's last year. His 2nd year, he's got two very inexperienced QBs.

1st year = senior QBs
2nd year = freshmen or inexperienced QBs

That is your pattern.
