Yeah practice mode has really helped my running game this year. I haven't heard of people using the momentum to their advantage too much. Where as your moving right along the line and see a defender coming so you pull left on the joystick, the RB then plants his feet and leans back to the left, in anticipation of the cut, and then the defender is almost on you and you spin back towards the right instead and he goes right by. When I do this it seems as though my spin is a little wider than normal due to the momentum and I'm able to spin all the way around a defender instead of spinning into him and having him either tackle me or fall off. I think when used right the momentum really helps the use of spins and jukes. I haven't really used the stiff arm or shoulder charge that much but from what I saw they are pretty great as well. Overall I'd say that from the blocking up to the running this is the best "running game" any football game has ever had.
