Guys help me understand the rules, never played the game, don't really understand the little intricacies like what Chad was hit with. Since Gronk is not on the Line of Scrimmage, should Chad be OK where he is? Also when I look at the play again, he was not on the line of scrimmage at all, how far back should you go if the TE is on your side of the OL? Help me out please. Thank you.
