Not making anything up - Childs visited no where else (maybe because he didn't want to, which I respect) and he was a career back up (a highly talented one, but backup nonetheless). He had no career in the NFL, going undrafted his senior year.Now you're just making stuff up. By all accounts Childs may have been the best athlete on the team. Would have played almost anywhere.A number of the running backs you mentioned above (Benning and Childs, for easy examples), would have likely "languished" as backups at other schools. Many of those Omaha guys were sprinters with good, but not great, ball carrying skills. Through a combination of great position coaching and a system that was wholly designed to outnumber defenses at the point of attack, these guys were given an opportunity to show off great speed - but they weren't really asked to do the type of running we ask of RBs today (let alone pass pro).
That was part of the awesomeness of that system.
I love the guy and what he contributed at NU, but he and Benning and a number of other NU IBs definitely benefited from the system. It's not at all clear to me that he would have been a starter "almost anywhere."
