So many great posts addressing this age old question could make for golden thread potential. Dog, I hope you have read these folks thoughts. They "get it". there might be politics afoot, but it usually only surfaces around the bottom of the roster, if at all. It is mostly a figment of those parents imagination, anyway.
As others have said, the kids know who needs to be on the field, and they usually are.
No worries. Enjoy the experience and stay posi+ive.
