Also include a schedule of this season games, higfhlighting any must see games in case any coaches would like to come and watch you play. Finally and most importantly send a copy of your grades and SAT scores. That's always a nice chemistry builder. Also try discussing some issues other than basketball that may be important in one's life. You will be amazed at the chemistry once we take a real interest in each others lives to show that one's friendship is not just on the court but off the court as well.
Chemistry is a powerful thing.
Good teams need it to win. I know sometimes some people can over do it. I do a variety of excerises. I workout with weights in the morning and a 2-mile run to start the day. In the afternoon, I always like to play pick up games with my friends.
