Eh let's not get ahead of ourselves. Yes, Emmitt played with a great offensive line, but don't take anything away from Emmitt. His ability to see plays unfold before they happened, along with his patience to wait for the hole to open, then his timing to hit the hole at the perfect time, his discipline to follow his blockers, they all played a huge part in his success.
I don't know if Barry had that same discipline and vision. Granted, I watched Emmitt 16+ games a year, and Barry maybe three or four games a year. I just don't like it when people attribute all of Emmitt's success to his line, as if any asshole could run for 1500 yards with that line. We all saw how ty the Cowboys played when Derrick Lassic or Sherman Williams had to sub in for Emmitt. Emmitt had superb discipline, vision, and intelligence on the field, perhaps more than any other back ever.
