I take a different angle on holding kids back in 8th grade for competitive advantage. To me, it can drift away from the wrestling ethos, which traditionally values earning advantage through effort, discipline, and courage in the moment you’re placed in. Less about restructuring the starting line.
I also think it can unintentionally overshadow the athletes who don’t optimize in that way but still compete with real courage against older or more physically developed opponents. Wrestling, at its core, has always felt less about engineered advantage and more about what you do with the circumstances you’re given.
If people approach wrestling with an idea of trying to attain perfection, from my standpoint, they're missing the point about what wrestling really offers.
