On the subject of discussing objectively with the official about rules misinterpretations, I believe Beeson said it best. "Present yourself correctly and you'll be surprised with results." Which are you more likely to come to terms with, a coach who keeps a level head or one that is so red in the face mad telling you how wrong you are?
I think it's fair that we as officials have to get background checks, but at the same time I believe we should throw out the Bronze Certification, Silver, Gold, Whatever... If you want to coach take the same tests our High School Coaches / Officials have to take, if you don't get the required 90% of officials that is needed for post season, then you don't get to coach in the post season. Also you would be required to retake the test every year just like officials. They would then know the required rule changes every year, points of emphasis, and just a general refresher.
How many times is a coach questioning a judgment call vs. an actual mis application of the rules?
