Coach, that is exactly my point. I am aware of the weekly limitations imposed on other sports. As you stated, you can plan ahead for that. In wrestling, you can't plan ahead like that (other than to just not lose).
16 man and larger brackets are not uncommon for one day kids tournaments. I have seen many kids wrestle 6 matches in one day. I don't think 16 man brackets are unreasonable for a high school tournament and the kids should be allowed to wrestle out the bracket.
I have no desire to attempt to change it (don't have that much conviction or energy). Just don't agree with it.
