reddevil,
If you read CHT's post carefully, the coach they followed was from SSC to MPSC, not MPSC to elsewhere.
Also, the groups that you are talking about, the "younger" ages, typically are not the ones that people talk too much about. There are large differences in what it takes to maintain consistency as the team develops and the players mature. There have been some very good teams at U12 and U13, even U14, that struggle as they get older. As players get older physical attributes tend to level out so then it becomes a more tactical game which requires a level of decision making that only comes with age and "development".
