this defenseless receiver rule changes from game to game
Im not sure goldson got him with top of the crown/forehead of the helm per these rules:
(b) Prohibited contact against a player who is in a defenseless posture is:
(1) Forcibly hitting the defenseless players head or neck area with the helmet, facemask, forearm, or shoulder, regardless of whether the defensive player also uses his arms to tackle the defenseless player by encircling or grasping him; and
(2) Lowering the head and making forcible contact with the top/crown or forehead/hairline parts of the helmet against any part of the defenseless players body.
