Eddie Lee! I-ver-y! It was a cheer.
It used to be in college football there was commonly a blocking back. I-formation, for example. When the OP says "best running backs", I think back to the time when you had a blocking back and a tailback--not necessarily two major ball carriers. I'm trying to remember who blocked for Ivery, Lavette et al. out of the backfield. They got a few carries, so they were running backs. That combo could be the two best running backs in the same year.
With last year's OL, we could have used some I formation blocking. I used to say that a good blocking back could cover sins of the OL. They did a pretty good job of using the TE to block the rushing plays last year. An NFL draft choice shows that to be true.
