Here's the open for the NFL on Fox. It reminds me a lot of the Sportscenter open because of the incredible number of layers that it has, along with the futuristic design, especially with the establishing shot. Unlike the open for Sunday Night Elements, which contains both animated and non-animated elements this open appears to be completely animated. The movement of the robots are very realistic to humans. This makes me think that they were using motion capture to either control or use as a reference for their movements.
The physics engine in the animation is also designed extremely well. An example of this is when the robots impact the turf causing blades of grass and dirt to fly up. Additionally, this piece also has great "cinematography". The 3D cameras get great coverage from a huge number of angles. The lighting in the piece also creates a dramatic yet realistic stadium environment.
