It happens to kids clear through their high school career. Every year in my sons regonial he had 3 kids ranked in the top 5 a a couple of qualifiers and then just some all around tough kids.
There were 3-4 kids my son beat several times throughout the year make to HS state but my boy didnt't

We all know that there are kids staying home from state that have beaten other kids from another district. That is just the way it is.

My suggestion is not wrestle for a week or two before subs and give them some rest and come in fresh.

Or maybe bribe him....lol
