Well, I don't have my new Rules Book but I know the only actual change was to the blocking below the waist rule Blocking below the waist (called cut blocks, NOT chop blocks, those are different and ALWAYS illegal) is legal in the free blocking zone and immediately after the snap. That means the lineman who cuts must do so Immediately at the snap, with no delay. The change is that is was legal to cut as long as the ball was still in the free blocking zone.
It's easy to get lost in the weeds of free blocking zones and all that stuff, but suffice to say the change is to an element of timing and that's all.
The points of emphasis are two things that need emphasized in the era of the RPO, but I haven't seen the final wording. They are intentional grounding and ineligible player downfield.
There are too many RPOs where linemen are going down to block, then the passer decides to throw after the linemen are well past the neutral zone. This is harder to call than you might think. My crew had at least 10 last season and I know we missed a couple. Some crews said they never saw it. I have a hard time thinking it never happened in their games.
Regarding numbers, it remains to be seen but it's not looking good, especially long term. Associations in the state are using anywhere from 4 to 7 officials on a varsity game. Obviously, the areas where 7 are used had ok numbers for now, but i know Northern Virginia, where the schools are bigger and, in theory (and probably reality) the teams are better, the number of officials has dropped to points where only four guys are on the field for some games. I don't know how this is possiblein today's game. Not sure if those are covid numbers that will rebound or not.
The pay is ok if you look at $$/hr only counting the hours from kickoff to 0:00. But we all know there is a lot more to it than that.
Getting new recruits is hard but keeping them is even harder. It seems there is an effort of youth coaches and parents to run off guys who are out there trying to learn to be officials and serve the game. If that's what they're trying to do, they're doing a good job.
I've been doing this more than 30 years and at the end of 2019, for the first time, I really wondered if it was worth continuing. In fact, there was a varsity game this past season, in April, where I just said if there are many more games like this, forget it, I'm done. That was entirely because of coaches and fan behavior. The kids were great,but it was a miserable experience.
Schools do not want to pay more,(because they're not rolling in cash, I know) but simple economics says that at some point if something is not done to make officiating the game worth the effort, no one is going to do it. Then what?
