Also Urban was all about evolving the offense and defense. He would bring in coordinators with a different style on both sides of the ball and see if they could mesh with what was existing there. New things were always being added or modified every season to keep teams guessing. It didn't always work but he seem to have the ability to fall back on a previous working model.
It just feels like at least on offense, Days offense is what the offense will be. I see very little to evolve it or to be creative. He needs a coordinator to come in and push the thinking with this offense. Im not saying it's broken but it's stale and that makes it predictable because of the years of tape of Day doing the same stuff.
