I am not sure if your aim is off or you just can't shoot. What you are saying is if "your" kids are not going to state and winning medals then the time they spend is not worth it. Nothing could be further from the truth. Nothing personal but I am glad you are not coaching my son with comments like this. High school sports, but especially wrestling is about teaching the value of hard work and dedication, growing as a person, handling your self in success as well as defeat. It is about getting better, setting "obtainable" goals and working toward those goals. Sucess lies in the journey, not the outcome.
I can say this because my son had some goals in his wrestling career. He never reached all those goals but has he looks back wrestling made him a better person, it made him see what he could accomplish if he was dedicated and put in some self sacrifice. Like I said he never reached all of thos goals but wrestling helped him grow and mature and that my friend is something worth while. So you should never take the approach like your statement above.
Well said, you learn how hard you have to work for something you want that bad. When your applying for medical school or vet school there are only so many spots no matter what excuse you have. Thats life
