"Masen Wake is a fullback in my mind, but he's actually played the majority of his snaps on the edge of the line of scrimmage in the manner of a tight end."
WikipediaAn H-back is an offensive position in American football. The H-back lines up similarly to a tight end, but is "set back" from the line of scrimmage, and is thus counted as one of the four "backs" in the offensive formation. The H-back, while similar in name, should not be confused with "halfback" or "running back", which are used to denote a separate, primary ball-carrying backfield position. The position was made notable in the National Football League (NFL) by the Washington Redskins under head coach Joe Gibbs, who ran a two tight end system. The position was named F-back when used later in Norv Turner's offensive system. The position is similar to that of a slotback.
