Agree with you 100%, JRut. I think most of us shake our heads nightly at the astounding lack of knowledge of the rules by players (somewhat understandable, but not very) and especially coaches (really not understandable).
I think it's more understanding why coaches do and say the things they do with regards to us and why they get frustrated. We have certain pressures, constraints and things we have to deal with, and they have a different set. If they understood ours and we understood theirs, I think we'd get along much better.
Like I said, I used to have one opinion of officiating before I tried it and I'm sure I'd have a different opinion of coaching if I tried that. But I'm not ready to do that yet.
If I do ever coach, I'll have a much more developed respect and understanding for the job officials do and hopefully that'll make it so I won't lose my mind the way some of these guys do.
