I did see one new thing not mentioned in the article about the running animations from the videos.
In one of the videos when the RB comes up to the back of his olineman he doesn't just stand behind or run in place behind him. He puts his hand on his back and pushes right up against him pushing the olineman forward then when an opening came to his side he was able to cut off the olinemans back to the hole and continue on.
Very nice - these are the things you notice when you play not all the other fluff like dirty jerseys.
