We say bring on the HS state placers that want to wrestle 14u, up a weight class and 'just for fun' - give our 8th grade boys someone to beat! There is just as much pressure for the 14u kids club kids as there is for HS kids.
If you're worried about your kid wrestling a HS kid this year, you probably should think about this being his/her last year in the sport. He/she just might be wrestling an almost 18yr old their freshman year.
