I think most chapters work on a negative behavior support system...you MUST attend x number of meetings, you MUST pay your dues on time, you MUST work x number of scrimmages, etc.
Seems to me the best way for a chapter to operate is on a positive behavior support system. You or your crew gets CREDITS for attending meetings, scrimmages, clinics, etc. Every sub-varsity game you work should mean something...if you want to work more playoffs, work more Thursday nights. Seems like a way for the chapter to have full participation...and objectively delineate who deserves to work later into the season.
It sucks to work hard and get shafted at the end. The crews who get "requested" by the coaches aren't necessarily better...they are just better at the networking game.
Not a whole lot of difference in your 1st and 2nd paragraphs. Same results; just worded differently. If you don't attend mtgs, work scrimmages, work subvarsity ... you don't get CREDITS. So, your rank is lower.
Same thing.
To 'work hard' is not the same as to work well. Some guys try hard, but just can't cut it. All the hustle in the world can't be substituted for excellent rules knowledge and great mechanics. On every play. By each member of the crew.
I question your motive in putting the word requested in quotes.

Are you suggesting that coaches DON"T really ask for certain guys? Roughly a third of our chapter's playoff games are by request.
Networking? By the officials, no. I was requested by a coach from a distant school for whom (and at which) I'd never worked. Nowhere close. In the pregame, I came right out and asked him -- why me? Turns out, he went to college with an area coach for whom I HAD worked. The distant-school coach called his college buddy and asked whom he'd recommend. The local area coach gave him a list.
COACHES are the ones who network; not the officials. Names of officials are exchanged at THSCA meetings. Phone lines and emails warm up when playoffs start. When you work a scrimmage or non-district game, you MAY be auditioning for a playoff game. That's happened.
Note that the audition does NOT entail brown-nosing. What is required is an accurate administration and application of the rules, proper mechanics, and treating both sidelines equally, professionally, and with respect -- whether it is deserved or not.
