I was lucky enough to see this match. I'm certainly not as knowledgeable as many on this thread.
It was a slam. The only problem I saw with the whole thing is if the kid could not continue how , by rule , can he then advance? Cant continue should mean can't continue. I think the spirit of the rule is to have kids that may be down on the scoreboard to not have a motive to hurt someone in order to advance. I get that. But when you put this in the hands of coaches to make that call not all coaches will react with any other motivation but to do whatever they can to advance their kid. Its a side of our sport that can get ugly, but for some its all about the W and integrity is not a major determining factor ,as it should be.
