****. I think you are sincere but you're right you are WAY ahead of yourself. I wouldn't even seriously think of this kid as a future pro. If you want to treat him that way for motivation fine, but you must be careful. Bear in mind, that ten's of thousands of kids around the world have this dream. Many are talented, many have great storkes. Only a precious handful will make it. There are SO many twists and turns on the way to a pro career, even those with the talent often don't make it for psychological, financial reasons or a lack of proper training facilities or injuries or....well just about anything. At his age and development, the road is so long. You must be careful, there are far more burnouts and dropouts and kids that end up resenting their parents/coaches(at every level and age) than kids who become top 100 players! The odds of him continuing down the pro path to stardom are probably about 1 in a million, and many of those factors you can do nothing about, so take the advice of those who said just keep it fun for him and try to keep him developing on track.
I can appreciate your enthusiasm though, it's a LOT of fun to watch a talented youngster developing.
The experimenting is terrific. In all honesty, this is the process the best take and how great strokes are developed. Not by a coach spewing endless templates and instructions on mechanics. A good coach will let his body and mind learn and simply nudge and point in the right direction. Let his natural strokes form.
I myself have struggled lately with a very promising 11yr old who is top ranked....I am not his daily coach, but the father comes to me for advice from time to time. He is talented and on track but I'm worried that they are to assertive that he is going to be a world beater, while that does give him a cocky arrogance, it may lead to problems down the road. Already he has severe temper problems in tournaments.
Anyways, also, bear in mind, that at the early junior level, personally, when assessing eventual potential, I probably look at strokes as the least important factor. Great strokes are wonderful, but if you're shooting high, you must look at other factors, athletic potential. Hand eye, quickness of hands and feet, balance, feel. Because even the slowest, lumbering pro is actually well above average athletically and you must be in today's game. Without this, you cannot make it and while you can prosper at the lower levels, eventually it will catch up to you.
