The retirement of Bruce Arians (via Yahoo Sports), means that Tomlin has to bring in a new offensive coordinator. It also means that there will be at least a slight shift in offensive philosophy.
Pittsburgh's offense is loaded at the skill positions, particularly at receiver, and yet they only managed to rank 21st in the league in scoring. That is simply not good enough.
There is also concern with Ben Roethlisberger's health moving forward. As he approaches 30 years old, Roethlisberger's body will not be able to sustain the high number of sacks that he has taken in the past.
Does this mean the days of Roethlisberger extending plays are over? No. However, there are some areas that the offense can improve to not only protect the franchise quarterback, but also to increase its scoring production.
Let's take a look at improvements that the next coordinator can make to improve the offense.
