You can tell very early if a player is excited about playing soccer (or not) - even as young as 5. It helps when the kid has someone that is playing with them at home - sibling, parent, etc. and spending time with them or have a goal in the backyard. Then, when they are around other kids, they get very excited just to play. At age 5, there are some kids that see a soccer ball as something they can "play" with, and other kids look at it as an object from another planet. Soccer is a lot more fun when you know how to do things with the ball - dribble, shoot, etc. And, for some kids, just getting to kick something is fun! Its the only time they are every allowed to kick anything as hard as they can, and be encouraged to do so.
You have to start somewhere... but as a coach looking at players, you can tell as early as 5 which have a natural excitement and which don't yet. It can always be developed though, even with shy or uninterested children if the instructor sets up the right amount of fun and learning for the kids.
How often should a year group change coaches? I see some clubs try to change every year or two.
No magic formula here - soccer development is the same as school... you have a curriculum that you want the kids to master at certain ages that includes different components.
At younger ages, it is about mastering basic skills, developing basic foot skills, small-sided play (1v1-4v4 situations). Some coaches have a lot of experience teaching this and are better with the younger kids.
At older ages it becomes more about decision-making, speed of play, advanced skills, role within a formation, developing physical and mental strength/competitiveness, which is a completely set of concepts to teach. Some coaches are better at working with older players than younger ones.
So it comes down to the coach - some coaches want to stay with their team as it advances through the age groups, which is good experience for the coach, plus he/she knows the players well already. But sometimes the coach will go through trial and error if teaching a new concept or needs to take another level coaching license to understand how to design a particular type of training session. Some clubs make coaches rotate every 2 years - so you would coach a team for U9 and U10, then be reassigned somewhere else, or take on another 2 years with a new U9 team. There's no magic formula, but every coach has their strengths and usually is better with a particular age group than another. So you want your coach to have strong ability in the age group where your player is.
Some of the best coaches at older age groups (even former college coaches) are not all that great when they coach teams of younger players because they expect too much too fast. But they have a reputation to stand on.
Any reason behind why coaches don't start certain players in games? DC rarely starts in games but does end up with a lot of playing time...if that makes sense. Thanks
Most coaches will start what they think are their strongest players in each game. Why? because they think the other team is going to start THEIR strongest lineup, so they don't want to put their lesser developed players out there and have a couple of quick goals scored on the team in the first 10 minutes. Once the flow of the game starts, eventually the opponent's strong players will come out, and the coach will feel a little more confident in putting his lesser developed players into the game without exposing his team.
You never want to match up your least developed players directly with a group of the other team's best lineup... it goes downhill very quickly.
There are a couple of ways to start games:
1. Strongest lineup (the best players in their best positions) - for competitive tournaments or against opponents you know will cream you unless you maximize your team's strengths (not good for long term development, but a good experience once in a while)
2. Semi-strong (best players in rotated/mixed positions) - when playing a strong opponent in a league game, less developed players still play but limited and their weaknesses are counterbalanced by other stronger players on the field
3. Mixed (combination of strong and lesser developed players on the field) - best "default" for most games - this is where you allow your players to really develop more evenly across the board
4. Semi-weak (least developed players in strongest positions) - when playing a lower end team that is equivalent to your lesser developed players (if you have them) - let them play without as much pressure - they can afford to make mistakes and learn from them
5. Weakest lineup (the "least developed players" in their weakest positions) - when playing a team obviously weaker than yourself or that plays in a much lower league, or younger age group scrimmage situation
So the coach probably sees your player as a reliable contributor, but would not be a part of the "best" starting lineup for the team. It just means that your player hasn't proven himself yet as "better" than the other players who are starting. That comes down to what the player is doing in practice in comparison to those other players... coaches take mental notes all of time of how players do in practice. It's impossible for everyone to be on the starting lineup, so it's good that your player is playing a lot. So, you don't need to worry about anything.
What do you think about players from other places who are quite obviously older than the rest of the children playing soccer? (i.e.: teams from some areas are enormous in height and weight, and sometimes look more like adult rugby players, than youth soccer players).
I think you see the disparity more on the boys side, with towering 11 year olds that have mustaches while others are still "little kids". There's not much you can really do about it when teams play each other - can you picture a team of boys all born in January 2006 playing a team of boys all born in December 2006? I'm sure it happens all the time. With pre-teenage boys you have to look at if the speed, skill, and physical level of the game and see if your son is in the right setting. Too easy or too hard, and he won't benefit. And it changes every year as the kids grow.
Eventually it evens out, but from 11-15 or so, you can't compare players by physical ability to see who is "better". you have too look at what they can do with the ball, which is not genetic. A 16 year old super athlete with no ball skills or touch cannot play at a highly competitive U17 team except as a backup goalie.
One of the best ways measure or evaluate players is TIPS (from the Dutch) - Technique, Insight, Personality, Speed.
Not size, strength, or kicking power. Often the 6-foot mustache kid is not developing technique, decision-making, or other elements of soccer because he's getting away with mowing kids over, and its working for now. But that won't work when every other kid also has their growth spurt.
