Talking to your Coaches

My son is 10 and has been playing football since he was 6. He has been a starter on both sides of the ball this entire time. I have coached in the past (never coached my sons team though) and wanted to get some feedback on some ways to talk to our coach without offending him or causing my son to hit the bench. so here goes.

After starting both offense and defense for the past three years my son is now only starting on Defense. We took a week vacation and came back to him being taken off both the special teams as the returner and starting offense as the full back. He works extreamly hard and does deserve to start. He really wants to know why it happened and what he can do about it. I need to speak to the coach, but when parents used to come to me about similar stuff it was always tough to see if they were doing it for themselves or for the kid. I certainly dont want to fall into that catagory with our coaches, they are really very good coaches. Just a note: one of the coaches kids missed the first week of practice and didnt loose his place from last year.

Any feedback would be great.
