if a defender even touches the facemask or cage of the running back or receiver etc. he's called for facemasking and yet the opposite never seems to be called. Every week you see a RB or WR put his hand out intentionally to block the defender in the mask, sometimes the fingers even grip, and yet they never get called.
I find that wrong. In last nights BC vs Als game, I saw the BC defender try to push Colborne out of bounds. Colborne had the defenders mask and even had a grip on it at one point, the defender end up doing the same and got the 15 yard penalty.
