You also have to consider that in a real GD setting, if you had an RB like this in a game and saw he rushed most of the time, you would probably see the defense tend towards more of a rushing defense to try to step him. So really the question I would like answered is what does his numbers look like if he is facing a defense focused more on the run than the standard 3-4 playbook is?
It looks like in more evenly matched games, his numbers are more realistic. I'm kind of leaning towards this is where we want to be with a disclaimer that everything can always stand to be tweaked now and again. In fact, I think if we could test with all sorts of match ups, you would want to have some high TKL numbers on your defense to counter a high ELU player. If that works out as a counter, then it really builds into the idea that you would want to find a high TKL DB as perhaps your SS to help against the run in these situations. That's the type of stuff I want to see with the new engine.
