In reply to: by the way, officiating was awful again yesterday posted by jt
If the pass is behind the line the ol can block someone trying to intercept the ball, as long as they are behind (McCaffrey 1st td). If the pass is beyond the line on an rpo the ol cannot be downfield more than 1 yard (game winning td there were ol in the end zone, ball was snapped at the 4).
So can't they push their defenders downfield as far as they want?
it's not supposed to be a run block look, that usually gets flagged.
Edit: it was a double team run block by the guard and tackle on the 3 technique. They did engage him at the line.
