To start off, there is no chance Marvin Lewis will be returning to the Bengals as a defensive coordinator. Cincinnati and Lewis have both moved on. This is more to see what the public opinion of Dom Capers as defensive coordinator is like.
This is because it has been reported that Jack Del Rio and the Bengals agreed that he wouldn’t be a great fit at defensive coordinator. Also, Dennis Allen decided to stay with the Saints after it was also reported that he could be a possible candidate for Cincinnati.
