It needs to become a topic for the mainstream media. Until the fans via the media put more pressure on the NFL, nothing will happen.
I don't think most people realize that at the heart of the problem is for lack of a better word, the politics behind the scenes. The refs union makes changes difficult. They do a lot of things just directed at protecting their job and their industry. They've always resisted technology which is why the replay rules have evolved in a odd way. They resist a disciplinary system with any teeth in it, again to protect themselves. They have a very large sense of arrogance and entitlement that almost rivals the Wade Phillips era Cowboys.
The NFL has ended up with odd workarounds. The booth officials as we found out were not in the union; however, they seem to be intimidated by the on field refs who it appears are from an employment standpoint are at higher level than them.
The NFL has Blandino who was never a ref in his life as their "boss" because the NFL wanted someone that was not the the "clique" with the refs but he has just turned out to be an idiot whose primary job is to go around explaining why certain call were made.
It is unfortunate that the NFL didn't just break the union and stay with college refs. I'm convinced those refs would have been as good as the regular refs by the 2nd season and would eventually be able to exceed them without all the nonsense involved with a union.
If you don't know, any dealings with unions are very difficult and their only reason for existence is to improve the personal lives of their members, not to improve their industry. Union are the reason that Detroit is a ghost town. Car companies just moved away to get away from unions that were impossible to deal with. The unions in the industry were also a big part of the rise of the import autos back in the last seventies. It was difficult in the late seventies to make cars when at guy whose only job was to install the battery was making $25 dollars per hour at a time the minimum wage was below $5 per hour. Unions were terrific when they first came into existence, before the government really put any controls on industry, but they've evolved to just lower lower product quality.
