Here the H-back is represented by the symbol, appropriately enough, "HB". The H-back position is like that of the "wingback deep" position previously described in a version of the single wing formation, and here is shown behind a wingback to emphasize that, although more often the H-back and wingback, if there is one, are on opposite sides of the set. It is possible to say the abbreviation "HB" is already taken up by the halfback. The H-back does occupy a position about the same as the halfback in the diamond formation of the 19th century. It is likely that "H-back" is a term derived by back formation (pun unavoidable) from the abbreviation for halfback, although arbitrary letter designation by some coach is just as good an explanation.
