I am the tallest on my team (another player about an inch shorter than me) I am 6’1 and 14 yrs old. Whenever I am at the park with friends or shooting around at the gym with my uncle and his friends I do just fine. However, once I get on the court and get the ball I freeze up and my muscles tense. I either loose the ball or just pass it immediately. It’s instinct, I don’t know why I freeze up any help?
