I know that you meant in general, which is only true when there is no apparent impetus for the blocking. Nothing could be further from the truth this season, nor last season.
You need to know what to look for, and not just summarily dismiss. Remember, assess yourself, and look to guidance for conformation. This voo doo conceptualization that blocking is akin to some sort of mythical legend is entirely a product of people just impulsively whacking it to long range ensembles without questioning it.
Last January was a prime example....people pinned there hopes to it and flipped, when there was never anything to support it. This led to the tragically flawed presupposition that least season would never recover, and we'd see an early spring.
