Losing sucks. Getting blown out however is when you have to worry. Your team might be tiered incorrectly, your coach might be packing it in, the talent on your roster might not have any chemistry. Who knows. Either way, talk with your wallet. If your kid is miserable with his current situation then leave at the end of the season. Food for thought however, sometimes you land on a winning team with a miserable coach or sketchy parents. You will rarely find the perfect situation.
