I first noticed this a year or two ago in the college game: they call way too many charges. It seems like defenders never have to be set anymore. I thought the NBA was still pretty good about block/charge calls, but there were so many calls this first week of the season that weren't remotely close to a charge. It's not just a bad call here or there but countless missed calls. The refs need to be "reminded" that a defender has to be set and can't just jump in the air and not even have their feet on the ground. I understand these bang bang plays are tough to call, but I thought the refs were pretty good at these calls until recently. It's getting ridiculous what they consider a charge nowadays.
