Well Mora & Co did select Edgerine James over Ricky... :), ha
If you say so, but 97 yards on 18 carries doesn't sound unstoppable. His teammate had a higher ypc on less carries. It also reported that Parcells actually got on Payton and told him he should be running Khiry more often, because his style resembled Curtis Martin.
I'm not an Ingram hater, but I agree with Mora as in he was not a special back. As you mentioned, he can catch, pass block, but I don't know if any DC game planned against the Saints saying "man we really have to stop Ingram and not let him beat us".
