I don't think Kelly limited Rees's play calling on a play-by-play basis, but Kelly discovered at a certain point that he had the talent to turtle up on special teams and offense and rely on his defense once he had a double digit lead. I think he didn't care about the eye test and was comfortable saying "reign it in" on the offense once we got a two possession lead in the 4th. I don't necessarily hate this mindset, because it won us a whole lot of games, but I do expect Rees's preference will be to pour it on when he can.
