If Joe Flacco has another offensive coordinator go one and done, he'd start to get abandonment issues. The last two offensive coordinators, Jim Caldwell and Gary Kubiak, both left the Ravens to accept head coaching jobs after one year on the team. Fortunately for Flacco, he won't have to deal with that in 2016.
Marc Trestman will be the first offensive coordinator to keep his job for two seasons since Cam Cameron in the 2011-2012 seasons. This means that Joe Flacco and the Ravens' offensive players don't have to spend all of training camp learning a new offense. Year two of the Trestman offense will certainly be better for the Ravens as they will be familiar with the offense and they should have healthier and more experienced players at the skill positions, with Maxx Williams, Crockett Gillmore, Buck Allen, Kamar Aiken, Steve Smith, Ben Watson, Jeremy Butler, and Breshad Perriman serving as targets for Flacco in 2016.
For the first time in four years, Joe Flacco won't have to learn a new offense. The continuity that comes from having Marc Trestman around for a second season will only lead to growth for the Ravens' offense in 2016.
