You changed your post.
There is no 'if". It IS allowed. And as long as its allowed there isn't much you can do to speed it up. Refs can stop the clocks as noted.
I would agree. But that would slow the game down more and there is no stoppage time in HS. Sounds like in the game where there were 12 that they were using the more traditional process of substituting.
I am sure these were by every definition "good refs". They made a mistake. And I sure they weren't happy with their mistake. I am guessing in a 5 man system that not every ref is responsible for every facet of the game. They split responsibilities I believe (I'll let a ref confirm or refute that). So even though there were 5 refs there, I think the one on the sideline is the one responsible for keeping track of the subs (actually two...one on each side). And the CR oversees the entire game obviously.
So even though in your eyes it shouldn't be hard to keep track of players we have an example where a mistake was made.
Fair enough. We all make mistakes. Just found it curious that it happened in a state semi game with the extra refs. I really don't care about the outcome of that game, have no connection to either team.
Just to give some context for this original post. I first posted about how frustrating it was to watch a Regional game called "by the book" and how I thought this was either a misinterpretation of the rule or that the rule should be changed. THEN, a week later the 12 players on the field occurred in the next round. I just found that kind of interesting (I think I used the word "hilarious" and got raked over the coals by MJ_SoccerRef)
