You should try to do what is best for the team as long as it is not detrimental to the wrestler's health. If a wrestler can't make the next weight class down due to a natural growth pattern, then they should wrestle were they are comfortable and still be able to help the team score points. In a case of moving up two or three weight classes, that is a challenge. I would think that if you can move down and win any challenge thrown at you in practice, then you should earn that spot and someone else move up. Whatever the outcome is, best of luck this season.
