I am a 14 year old 5 ' 8 sf/sg. I am a very good shooter, defender, and rebounder.In middle school i played sf all three years so i never focused on my ball handling. I am a freshman now and will tryout for jv mayb varsity, I know that since I am pretty small and skinny I will have to play guard. I am descent ball handling, but I want to get excellent. Any help?
