I think maybe the most important addition could be which punter we choose to go with. That position could make or break how well our defense is set up, how they will need to defend Poor punts, blocked punts will give short fields and hard for the defense to cover not to mention tiring them out....on the other hand a punter who does a lot of in side the 20's, long coverable punts will just give the D a much needed lift in games. Hekker could be so good that his position was taken for granted.....
AR and Wagner IMO just add new dimensions to already proven areas, this new punter could be the game maker/breaker over the course of the season.
