That seems like the path he should want to do anyway get a good solid year under his belt as an OC with a solid offense from the offseason through, plus more experience working with a good HC at a high level in the system.
Um yeah that absolutely makes a difference, good coverage forces the QB to hang on to the ball and gives the pass rush time to effect the passer. They both work together.
I know he chose to skip his vacation to come back, but the whole off the couch narrative seems a little excessive to me. The guy has basically been with the team the whole season.
