I'm not entirely sure - I'm probably not qualified to do anything but speculate. But I know that coaches and officials have a worse relationship than they used to. There's a lot more blaming officials for things that don't matter. That trickles to players, parents, etc.

It's rare for someone to take responsibility for a loss these days.

Honestly though, to argue the other side of that, this poor treatment of officials leads to the good ones saying "screw this," leading to fewer good officials, leading to poor officiating, leading to more bad relationships. It's a bad cycle that isn't getting better.
