how can i get better

Question
Hi,
So I'm 5'6 and I wanna be a point guard for my sophomore team in high school. i basically play basketball for 5 hours everyday. right now i ask you on what i need to improve and what exercises i should do to do this? i will give you some of the things i do and some weak points.
1) i shoot about 50-100 3-pointers a day and avg about 30%
2) my free throws are 67% i basically play 21 to try to help this out
3) i need help on driving in on the defense. i sometimes get nervous when i drive in, but the time im not i just get blocked or can't break the defense.
4) i need help on blocking shots (even though I'm 5'6 i would like to do this)
5) i need help playing man-to-man defense
6) i can't jump high, but i am fast.
i have so much potential and am willing to learn these. are the 5 things that trouble me most I'm my game of basketball
thank you for your time.

Answer
Hi David,

I'm sorry I really can't answer your question. My expertise is not in conditioning but rather basketball rules and regulations. I'm sure if you scroll back through other experts in the "Basketball" category you will find someone much better suited to answer your question.  Good Luck!!
