My advice to you is: Just practicing won't help, practicing right will. When you practice think about what will help you the most. For me it was seriously learning how to shoot. BECOME A SHOOTER. Seriously. Best thing to do. ANYONE can learn to shoot. I started to play basketball in like 8th grade. Plus i skipped a grade so i had a disadvantage all along. Plus i'm an all honors student who practiced ONCE A WEEK. I tryed out and somehow i almost made it lol. I shot 4/10 freethrows, 2/10 spot shooting and almost made it. That was because of my ability to play tough and my ability to drive. That was my raw talent. However, now because i just practiced shooting, i make about 90 percent free throws and i can swish threes easily from 2 feet behind the line. Use your time wisely and just pass up those one on one games. Go and practice. After, go out and beat the guy with your shooting.
