Go back and watch any game last season. Quite a few times per game you would see Travis and the entire team check with the sideline.
I think Travis was told to either run the play as called or he had the option of checking with the sideline (Dave).
Outside of that Travis was pretty much on a leash because Christensen had no faith in him, nor did he ever try and put in the effort to build that faith. Christensen wanted HIS guy in there, that was painfully obvious.
Travis now has an OC that actually WANTS to see him succeed.
