The runner was making his way to the second level and the defender was only 2 or 3 yards from the ball carrier. Now Smith catches him with the perfect block, if no block the defender catches the runner and only a short gain. These Refs are calling any hard hit a foul. It is time to teach refs what is a foul and what is not and stop these refs from being cowards and stop letting the NFL office decide how they call a game. I bet this block would be a play of the week block if it were last year.
