In our house, baseball/softball rules. It would not be a hard decision at all for my kids. Reading the responses and your question brought back an interview I read about sports. Cal Ripken talked about how he tells his own son to put away the glove when the summer is over. He then goes on to talk about how an athlete uses muscles, coordination, and experience from many different sports instead of just one. Cal Ripken then talked about how he is alarmed at a national trend where kids as young as 10 are starting to play just one sport year round. This is leading to burnout, sports injuries (using the same muscles all the time) and other problems. What skills you learn in football, basketball, baseball, track ect will help in wrestling. I know that my son does basketball and wrestling right now. The basketball practices and games gives him endurance for those tough wrestling matches when it comes down to the wire. That is just one example of how one sport can compliment the other. If he can do both without any conflicts, let him do both. Just my opinion.
