i don't think it is a weight DISCRIMINATION thing. it's a COMPETITION thing.
i think everyone on here sees your point, but understand that if you are 10 years old and weigh 130lbs the law of averages is going to play against you. if you want to compete, you might have to COMPROMISE.
i haven't read a single post on here where someone thinks it's OK for big boys to wrestle up. BUT WE ALL KNOW THAT OUT OF NECESSITY, IF THEY WANT TO COMPETE, THEY WILL NEED TO BUMP UP.
little guys bump up too, ask around. it's been a few years but we had a 14u that weighed 75lbs- he never wrestled in a bracket less than 95lbs until subs.
