Go watch him wrestle in college at 184lbs. It was a completely normal and healthy body weight for him. He actually moved DOWN to 184lbs successfully and stayed there for two years.
He only started having weight cutting issues after he moved back UP in weight after leaving OSU. Not having to make 184lbs gave him the leeway to be less disciplined with his diet, he went overboard, which led to him trying to cut so much that it caused kidney issues.
He could 100% have competed at 185lbs, he just has a self-admitted bad relationship with food.
