Instead there are guys like Emmitt who yes had a great OL but took full advantage of it on his own fantastic vision and his short space ability to turn a body or shoulder tackle into an arm tackle and then run through it or to reach out and grab an arm and redirect it as he ran past. There's a reason the single season TD records haven't been held by big RBs. Only 2 of the top 10 are over 225 lbs and none over 230 lbs. I use Emmitt as the primary example because he was never a CJ scoring off speed. Emmitt was a power RB who ran right up the gut and played at his heaviest at 215 lbs.
But he had terrific leg drive and could push the pile when he needed a yard
