My brother was an 8th grader last year @ 130lbs and he placed 3rd @ state in 14 and under the kid he lost to placed 1st who was also an 8th grader both will be in the 14 and under division again this year. The kid who placed 2nd was a highschool state champion. I think an 8th grader can hold his own if he is prepared and is good enough.
