I have found that I get more informative answers if I leave out the 12u in my post, and in this case I was thinking about ramification further down the line and was this "normal" farther down the time line, so it seemed okay to leave out the 12u.

I know and I'm sorry I called that out. I think it is great that you are making it a point to become so well-informed ahead of the curve. (although, in this case, if he is also the 12u coach and plans to do that with your son, it becomes an immediate concern as well.) Admittedly, part of me is still trying to keep you from getting too far ahead of yourself so that you get full enjoyment of each age your son goes through but part of me was really curious as to what this coach's influence was on your son. I was hoping maybe it was just a passing casual conversation and, perhaps, things were lost in translation a bit. If this thread goes sideways, my apologies. As I mentioned, there are several other good threads on the topic you can search.
It is less and less "normal" further down the line.
