the number one thing is get a ball and get on the court. no shots, just dribble and get your rhythm back. dont watch any videos of anybody. your game is your game. as you get more confident get out and dribble around town while walking to the store or where ever. start playing sround the worl by yourself and build it up. once it all comes back you should get in some pick up games and do it for the conditioning part. do lots of push ups, pull ups, crunches, squats, step ups, and sprints. lots of layups and free throws.
as a varsity coach, i say get your feel back and stay motivated. critique yourself until you can get with a coach that can help you out. you can practice all day and not know how to prctice or what to practice. your love for the game will get you to a point you need to be and more. when youre ready, find better players and get involved in a few pick up games to challenege your ability. go try out for a league, club, or rec center team. make networking connections happen; if youre in school, get to know the b-ball coaches and talk with them.
