4. Marty Mornhinweg
It is hard to give Marty Mornhinweg a full rank because he is still coaching, but I will go off of last season. He took over the play calling duties once Marc Trestman was fired in week five. Much like Trestman, the offense could not find an identity and struggled during the season.
The offense finished the season ranked 28th in the rushing attack and 21st in points scored. That is not good enough to be a contender in the league. They continued to rely on Justin Tucker to score points and get them out of tight situations. It seemed at points the offense was more comfortable kicking field goals than scoring touchdowns.
The main issue was the pass happy philosophy. Mornhinweg did not want to run the ball, even with two promising backs in Terrance West and Kenneth Dixon. Joe Flacco threw a career high 672 times and that was not to the benefit of the team. If the offense does not produce this upcoming season, there is a good chance he could be on his way out very shortly.
