My issue with the refereeing hasn't changed in years. The problem is that for football the referees are not professionals.
It started with the NFL. My father has a couple books written by ex-officials back in the 1990's. Both officials don't advertise it, but reading their bios they were involved in insurance sales. They had a regular job for Tuesday-Thursday, would usually work only a half day or less on Friday so they could fly out that night. Saturday would be spent meeting with the rest of the crew and preparing for the game and after the game sunday night they would rush to the airport since they were expected at their regular job on Monday.
And this philosophy of how to deal with referees obviously trickled down. If you want check around the county you live in and try to find how referees for the local high school games are selected. In most places you have to show up at 3-4 meetings/classes and pay to provide your own uniform and you too can be part of a crew refereeing JV football. If you do that and are somewhat successful (you last more than 2 years in other words) some of the college conferences may approach you and offer to hire you for one of their crews.
But its still part time work. You'll fly or drive in to referee the game and then head home to your regular job.
So what does this mean.
1) there is no guarantee referees agree on the application of rules from crew to crew.
2) there is no official requirement that referees be in shape (most are, but its not required, and many aren't in good enough shape to keep up with 18-21 year olds who are trying to get the attention of NFL scouts.)
3) There is almost no vested interest in referees improving.
I keep suggesting that if we want to see officiating improve, the sports have to go away from the philosophy that this is a part time job. The NBA, NL, AL and NHL have had to do this because of the number of games played per week. They can't hire a bunch of insurance agents and lawyers knowing that these men have weekends free to officiate, but football still tries to find men who love the sport enough to give up their days off to referee, and it shows.
So my solution
A) Pay referees an annual salary and hire them with the understanding that it is a full time, year round job.
B) referees will be expected to go to regular classes/seminars regarding the rules and proper application, these should include extensive film study both slow motion and full speed to review referee angles, locations, and who should be throwing flags for what kind of penalty. Too often we see officials who are out of position throwing a flag on something that wasn't in the zone they were supposed to be watching.
C) Make it clear that referees are expected to be in shape and that they will submit to regular vision, hearing and physical exams.
D) Reports on officials performance can be kept secret, but the reports do need to have teeth. An official with multiple "poor" reports in a season should not be invited to have their annual contract renewed. And it shouldn't take the fans marching on Pac-12 HQ to generate a "poor" report. The performance reports must be honest.
Odds of any conference doing this. 0.00% Heck the NFL tried to use replacement referees a few years ago because they didn't want to pay their current referees, and they do pay enough that most referees could retire from any part time job if they wanted.
