Like I said before, there are no disadvantages for wrestling. Also, if your middle school and your high school share a room, the middle school team is out of the room by Christmas. One team probably has to practice late, most likely the high school team. I always feel like if a kid gets an hour or so to do something else, he may have a difficult time deciding to go to practice. I think starting a high school practice at 5 or 530 hurts the high school numbers, without a doubt. There is no doubt that it is the best thing for wrestling, and I do not see how it harms the other sport.
