I guess next we'll be only letting wrestlers who are the same year of age and born in the same month wrestle each other, that way we know for sure there is absolutly no advantage given to one kid or another.
Which brings me to another point, there is no rules in USAWKS by-laws that prevent a club wrestler from practicing every night. They generally don't because there are few kids coaches who would open up the room 5 nights a week, and probably even fewer kids who would come in every night. So I find the example of High School/Middle schoolers being able to practice 5 days a week is a very weak arguement. If a 8th grader really wants to be able to compete with a kid who just months older than him but a grade ahead based on his birthday, then perhaps he should find a coach willing to open up the door for him to practice every night, rather than a coach who complains because their kids are disadvantaged for only getting to practice 2/3 nights a week.
The one thing I have noticed is, the kids who are talented and hard working, almost always win regardless of a few years age difference ie freshman who beat seniors.
