So, I’m going to take the plunge and do some high school this year, so I’m looking at the rules () book and the description of the dual system. (First whine: they really put dual before diagonal!) I find the drafting makes IFAB look like Hemingway. One should be able to draw a line between the two officials and the ball “at any time”? WTF? The T is supposed to be even with the GK when he’s holding the ball?!?!? Which of course contradicts everything else in the section!?! And I’m still trying to figure out how the trail ref will sometimes have to become the lead and rule on goal line plays on the right? Sigh. Are there any good resources on duals that make sense? (I did dual games 30+ years ago, but we were essentially doing the “two ARs with whistles” version, which is obviously not the way to do it properly.
