text: well it partly depends on what grade ur in.. if 8th grade or soemthing 5'3 is fine, but if hs.. then it might get a lil tricky..\n\nok but watever. coaches may judge height, but they mostly look for skill (both defense AND offense). they usually tend to look more at offense, even though some claim that defense is most important. the reason for this is that it is harder to look good at defense than it is at offense (good defense = opponent not being able to score.. but its less obvious and less breathtaking than someone making a 3 or dunkin the ball, etc)\n\njump shot-- u need proper form first.. then practice for a while.. competitive practice is the best, try playing ur friends (who have decent defense) proper form = when u lift ur arm, ur elbow is at 90 degree angle.. always hold ur follow thru\n\nspin does indeed help ur shot, but u shouldnt really worry about that. spin comes naturally once ur get ur shot right \n\nto get better shot, work on ur triceps (work out). working out throws off ur shot, but once u practice and get it back its worth it. also, try to shoot under pressure with a friend as well\n\nsome of my favorite drills that i have done to become a great defender are = towel jump, lunges, and just jumping as high as u can. a bball and a hoop is really all u need for offense.. practice layups.. not just ordinary ones, but jump stop layups.. layups at full speed. and also work on both hands\n\nfor guarding, explosive side to side movements are ESSENTIAL. as i said before jumping and towel jump will help this greatly (towel jump = place towel on floor and jump side to side of it\n\nalrite good luck
