Mike & Marvin will give 2018 a MULLIGAN - See 2019 as year 2 of a 2 year PLAN

If Marvin stays, here's my crystal ball vision...
Bill Lazor is replaced by Hue Jackson as OC. The offense was best under Jackson and he's familiar.
Marvin's old LB coach from back when he was DC at Baltimore, Jack Del Rio, is brought in to take over as DC. Del Rio had really good years as DC in Denver and being a former player and coach of LBs, he will be viewed as being able to turn around that position.
Hue takes over for Marvin as HC in 2020, and Hue will get to pick his own QB and OC.
