Sometimes referred to as the 'power back' position or 'in-motion tight end', the H-back is a cross between the tight end and full back positions. This position is responsible for blocking, pass protection and passing routes. Very rarely does the H-back run the football.
H-back should not be confused with the halfback position. The H-back position is usually played by a tight end. The position was perfected by coach Joe Gibbs to counteract the pass rushing ability of Lawrence Taylor in the 1990s.
