Hmmm. I would have sworn I posted my answers to S-B Quiz 8, but I don't see them, so I must not have.
Well, I got 7 of the 8 non-replay questions. But, I didn't read Q4 the same as S-B intended, apparently. (I had a BIB.) Nothing in the question led me to believe that the Team A blocker had maintained contact, and the block in the back was just a 'continuation' of action. Considering the block was 4 yards outside the 'blocking zone' (not tackle box), within which blocks in the back are allowed, I would have a hard time believing the block was continuous. And, considering the ball has left the blocking zone, I don't see this block as being legal. This being "in the spirit of the exceptions" is very much news to me.
What's next? Flopping on a prone/supine opponent is OK?
