While I appreciate AAA's enthusiasm for a particular club team or younger player (a reoccurring theme of his), lets look at the big picture as the younger players make the transition from MS-age club to the HS game. This is not singling out any one team or particular player. This is an observation (over a dozen years of seeing this) albeit unqualified, about how new freshmen transition to the HS game.
In general one age group compared against itself such as a competitive U15G is only one data point. Let us remember that HS soccer is about 4 years of a mix of ages and abilities. Someone said that the "usual suspects" of talented HS teams are mostly D2, D1, and Premier level players rolled into one school team. The best HS teams seem to have the most D1 and Premier level players as a rule rather than an exception every year. These teams seem to come from populated areas with feeder programs. Every year its the same teams, and one or two new players come up that catch the eye.
Younger players will adjust to the HS game. Some will do it quicker. Some will not like the fact that as freshmen, there is a "rite of passage" that all seem to go through, and they are again on the bottom of the food chain. Maybe its called paying dues in some circles, but in its purest form, it is a reality check. Some players will quickly realize there are other players just as good as they, possibly better.
Some MS age club teams did not prepare for more physical HS, by playing easy schedules. The HS game is faster, more physical, more sophisticated than a middle school age club match. Some of the older players were young standouts as well, having grown, and improved over 3 years. Younger players can learn from them, and older players can see how hungry younger players are and not be complacent.
Older players are mature physically, and emotionally and have been put through the test of a few seasons. They may be hitting their stride as they push to make it to the next level after HS. The new players entering HS might have been standouts on their respective club teams, but now, they have to bring their game up and as one coach has said, "grow up" to this level as many have had to do in the past. Younger players no matter how good amongst their own age, will have adjustments in the transition to HS play and this takes games, nature, and nurture.
There are very distinct challenges the player coming out of middle school will encounter at the high school level. Playing against faster, bigger players is a given. There are also different systems, broader tactical awareness, and possibly playing different positions and realizing that they will have to play as a team. Mostly they have to continue to believe in themselves when put to the test, and have confidence to try new things and work with new players. Each year has its standouts, and we should be cautious about hyping up new younger players because we do not want them to fail.
We should keep a watchful eye on our younger talent, and nurture them so that they can succeed in time. They are the future asset. Lets cheer them on as many have been pressed into starting roles but let us not put them in a position where if they do not achieve instant success, or live up to impossible expectations, it would be a rougher road ahead.
