Its time for my annual one post here in the forums.
This year I found something I think everyone should take a look at. The NFHS does have illustrations in the rule book but they are fairly small and in black and white.
The link below is a PDF file compiled by wrestlingref.com that has full color illustrations covering many concepts in the NFHS rule book. I encourage you to check it out.
Really worth looking at for High School Coaches, Little League Coaches, Parents and Officials. Great Resource that unfortunately the ones needing to study it, won't.
