I have seen so many top notch wrestlers fade away, or just flat quit because of "burn-out". The most common thread amongst them was the screaming parent at matside and AFTER THE MATCH. The kid knows if he screwed up, the parents dont have to keep reminding him. He has enough things to battle, let it go, smile, and remind him you are on HIS side.

For long term, basketball is a good thing. The more sports a kid is exposed to the more they will see that wrestling is the ultimate sport. Both my kids have done both at the same time. After playing b-ball, they almost always come back inspired to wrestle. Last year the youngest played a full season of b-ball and still had time and energy to win 12 tourneys including the STATE CHAMPIONSHIP!!!!

Like deanstraus said "its not a life and death decision". When the kid makes it, it will be his and he will be the one that pushes to make it happen.
