If the quarterback were to drop kick he would become a kicker and not a quarterback. The roughing the quarterback penalty would change to roughing the kicker.
Sacking the quarterback is not, by definition, roughing the passer. A sack occurs when a defensive player tackles the quarterback when he is behind the line of scrimmage. Defensive players are also credited with a sack when they force a quarterback to run out of bounds while still behind the line of scrimmage. Roughing the Passer is a penalty call. Roughing the Passer occurs when the quarterback is stuck by a defensive player after releasing the ball or when a quarterback is struck in the head/neck region by a defensive player. So a defensive player can be called for roughing the passer while sacking the quarterback if he hits them after the q.b. has released the ball or if he hits the q.b. in the head/neck region during the tackle.
