I'm sure it was pointed out but the biggest change I saw was we used play action a lot more than in previous games. The other HUGE difference was takeaways. We intercepted twice and recovered a couple of fumbles (twice when they were in the red zone). If we don't get those takeaways, we don't win this game IMO.
Also a lot of designed roll out drag plays to the tight ends. They were incredibly effective in the first half. Kamara’s injury changed the entire offensive gameplan, it seemed.
