For his career, Ivory is averaging an astonishing 5.1 yards per carry (compared to the 3.9 of Ingram) despite the fact that when he's in the game it's a telltale sign the Saints are running (74.9 percent of his snaps were on running plays), letting the offense key in on him.

I am not lamenting that we traded away Ivory, but when you see he still managed over 5.1 yards a carry even though his carry-to-snap ratio is a full 15% higher than Ingram (74 vs. 59), the "Ingram always faces 8 man fronts" argument becomes pretty much indefensible.
