At the end of the day, after a tourney, it�s you and your kid. You are either there to enjoy his/her success or to help console them. You do what is right for your kid. Your kid being at the weight that is right for him will do all you can be expected to do from a team standpoint. Any coach that asks more, is looking at it from an individual standpoint - HIS as Steve just stated. Remember the coach always has next year, the individual wrestler may not.
In practice this may be a team sport in terms of helping to prepare practice partners and so on. But once on the mat it is truly individual - one on one - with the help of 2 coaches.
Will has been right on this for years.
