Do not allow the kid with the disruptive/poor attitude to be on the all-star team......all that does is teach every kid in your league that if you are talented you will be rewarded, regarless of your attitude. And isn't teaching what it is all about? It will also teach that kid a lesson...eventually he is going to have to learn it. Kids with poor attitudes should not even be nominated to try out for the all-star teams....their coaches have not properly taught/disciplined them yet.....again, eventually the kid needs to learn that his behavior does not justify rewards.....why not teach him that lesson now??
