I could probably add Garrison Hearst, Darren McFadden, Tiki Barber, Cedric Benson, and others to this list of guys with early careers where they didn't have a high ypc or a lot of long runs and turned into fine runners in this league.
I understand staying away from Moreno if you're risk averse, but I don't think the argument is settled at this stage of his career. I think Moreno is one of this pivotal players that could make or break teams.
