I need some advice I play for my high school team we only get 50 mins to practice and no practice at school because the other basketball always have to practice and, both of our coaches always have to leave to go to their classes to teach so we are left to practice so tell me since the coaches are gone we type of drills can we do to help us get better because we already know how to do a lot of the fundamentals and some more the people on our team think they are better than the rest. when somebody mess up or do some thing or don't understand they want to laugh or get mad and, start yelling. Most of the time the coach doesn't do any thing about it. So what can I do???
