Here, let's put it another way:
Emmitt was a ferocious between the tackles runner. He attacked the A and B gap. Gogan, Tuinei, Newton, Step all led the way for him, sure, but after he got to the second level, back then, OL were usually left behind. Only recently have OL been taught to reach that second level. Still, those fellas mauled mofos.
Sanders was a sweep or C gap runner. He swept out and took off. That's why he met so many DL behind the LOS -- cuz he had no OL in front of him anymore, he pushed out too far to the left or right, so as to give his natural ability it's best way of being used.
In Dallas, while we did have some awesome tackles, our bread and butter was right up the middle baby. Right up that arse hole of the DTs position.
Sanders in Dallas would be a whole different deal. A whole different style. We cannot predict what he would have done here. Emmitt was the goat between the tackles runner of the 90s, Sanders outside the tackles.
Emmitt also blocked. Emmitt also could be relied on to catch out of the backfield in an era where RBs weren't asked to do it too often. It is much more employed in today's NFL.
Barry, higher peak. Emmitt, more sustained greatness. Emmitt GOAT. Guesses at what, who and who would do what here are purely subjective and an insult to our all-time great, imo -- in the same vein as those folks that use our OL against him.
