Yeah. To me, for the most part, you get a guy who is NFL caliber and you hand him the ball and stuff happens and mostly success depends on the scheme and blocking and complimentary talent, with some being a bit better than others. Which could probably be said of every position outside of QB. And yet some players at every position transcend scheme. I just think that is less the case at RB. I'm not denying it exists. I just think the gap between those transcendent guys and the other guys isn't as wide in the actual impact on winning and producing (or preventing) points. And yeah, like you mentioned, shelf life.
