The question you need to ask yourself was is he being caught from behind when breaking into the open.
I can tell you the answer is no. I had Eddie Lacy rip two monster TD runs. One on a screen and the other when he turned up-field on the edge and down the sideline.
It's too powerful at 0 this year. You feel it's slow because we are playing on slow speed which will give that feeling of running slow.
I suggest you turn that threshold to 25. That is where I am probably going to start my testing on it tonight.
