As I understand it, the H-back position is defined as a hybrid between a fullback and a tight end. I don't think that describes Brian Leonard, who really is more of a hybrid between a running back and a full back. I think if you're looking for a player on the Rams' roster that would have the best chance to be used in that Cooley H-back role, it may be
Joe Klopfenstein. It seemed as if Linehan started to do this last season, probably in large part because of a lack of a true fullback.
