Not even close to the dumb idea of playing down a grade and thinking that college coaches wont notice.

The truth is being misaligned will make it harder just like it'll be harder if you are forced to play up. Both would be an extra hurdle to overcome. Not impossible in either case for the talented/hardest working but it would stymie many others in either situation. Interestingly, with how it's shaking out, we'll have clubs some clubs that go with grade and the oldest and others who make it case-by-case.

Correct being misaligned will make college recruiting much harder. To address there are two options. Play up with your grade or get held back a year in school. Either way you'll align grade in school with level played in club. Most rational people in this situation will choose to play on the correct grade team.

Why go through all the challenges of being an oddball. Just play your kid on a correct grade team from a young age. When it matters they'll be used to playing at the grade level college coaches are looking for.

That doesn't mean you always need to play with your grade though. Especially for girls when they are 14 or 15 they can realign to play with their grade. They will be done growing at that point and the RAE effect is much much less than it is when they are Ulittle ages.

Thats a lot of extra effort just to use rae to justify playing on a grade down on an A team. You dont think these type of players wont piss off correct grade parents? You dont think these type of players wont become a problem for 8th grade teams when they're playing HS soccer for 3 months during the season? You think correct grade teams will welcome a less developed player from a lower grade team?

Switching teams isn't extra effort, it is often what is required as kids get older to put them in position to play in college regardless of being misaligned or not. Others parents are always pissed, nobody cares, welcome to travel. If you are positioning you kid to keep other parent happy, you are parenting wrong. Players aren't welcomed to new teams, they just show up. Thinking a team is some kind of democracy is your problem, it doesn't work that way.

You are completely selfish and wrong. Coaches / Clubs will filter out parents like you after a couple of seasons. Seen it happen multiple times. Unless your kid is a unicorn which I doubt is the case since all you want to do is play down.

In sports, following the rules isn't selfish, it's competition. Saying someone is selfish because their August girl is better than your Sept girl is loser talk.

I dont know where you got the the Sept thing but 1 month between players wont make any difference.

Sure you go and try to bend the rules to your kids favor all you want. Snowplow away. But don't be surprised when playing down that correct grade parents get tired of you. Also dont be surprised when you try to play your kid up at u14 for college recruiting and the team is full.

You seem to think that everything happens in a vacuum and that your actions wont generate a reputation. Just like with college coaches you're not going to sneak by playing down. There will be repercussions.

These parents aren't filtered out. They club hop and if they're kid is good enough, they've got them on the top MLSN/GA/ECNL teams. Those clubs cater to these parents, BTW, because they all are ruthless and play to win. By recruiting the best players and winning the most, they keep their college pipelines strong as well as the reputation.

I looked a little closer. There isnt any data used un the article. The author just cites other authors picking and choosing quotes that support their opinion.

I take that back the author went through NCAA division 1 websites one by one creating their own dataset. I cant see any issues with that. No way that a poor researcher would only include the data that fits their narrative.

Materials and Methods
3.1. Participants
The sample consisted of 1417 Division I volleyball athletes, including 1253 women and 164 males. Secondary data from the 2020–2021 school year were collected from the official athletic department websites, including 116 out of the 334 Division I women’s volleyball programs (represented 37% all DI Schools) and 12 out of the 48 combined Division I and II Men’s volleyball programs (represented 25% of all DI/II schools). This represented all the publicly available data at these levels and included, at minimum, each athlete’s birth month and birthday (see Supplementary Data File).

I guess you didn't see the part about how it represented "all publicly available data." It's just ... reality.

More like all public data that they wanted to represent. Theres a reason people tend to use the same datasets for things like this. Not their own hand crafted screenscrape. Its called credibility.

Just like from the beginning of the article. It was obvious that the author was looking to prove their opinion. They weren't interested in letting the data show whatever it shows.

You are even more opinionated and aggressive because you don't like the results.

Is this your first rodeo reading a paper? Duh, researchers have to pick data to evaluate.

Fine make your own dataset. It will be rejected because it has no credibility. Much like the volleyball paper you cited.

He's desperate to push this paper down when it is the first piece of research that looks at both club and school cutoffs. He just doesn't like the results so he bashes it.

HAHAHA 😆 😂 😆

So now not only are you advocating playing down you're also advocating club hopping to get what you want.

This is why your kid will never play on a top team. You're always going to be on the oddball losers team with all the other oddballs and losers.

It's not one month, for Aug and Sept kicks playing up a grade, they would be the youngest by 13 months compared to the oldest. Remember that char you showed where December births had the few est pros. It's facts like this that show the right path to excel. Bend the rules. You funny.

No, if you get your kid on certain clubs, your kid first of all earned it (it's survival of the fittest at these places), where parents will drive their kid 2+ hours a day for practice AND they get pretty much ALL their players to college (most D1s) and play in the playoffs most of their age groups every year. It's YOU who don't know what it takes for these places. They are like college before college.

I have seen the club hoppers come all the time. Clubs welcome them with open arms and have no problem pushing all the other kids on the team down a peg. You what the parents say? Nothing, because they know that's how sports works from rec to national teams.

Ok, be August or January/February, as the oldest and avoid being December/June/July as the youngest depending if SY or BY.

Makes sense and fits the data.

With stats from a video game! If I wanted to attack the data -- but I don't unlike YOU. There's a better explanation -- the US has switched its birth month system so of course it's going to look like this. That's why the volleyball is more interesting. It's of actual college players, not pros and it specifically looks at different cut-offs (not done in the medium piece) -- which make it more of where soccer is headed now that it's back to SY.

Heres part 2 of the study that show exactly the opposite of your nonsense articles without real data try to show.

https://medium.com/@giacorada/what-impacts-the-success-of-a-professional-soccer-player-14a2ab4f852a

"Finally, it appears that birth month (at least according to our models) has a minimal influence on the success of a player. However, while the impact was small, it was still found that players born later in the year had a positive impact in each position group’s definition of success. This is fascinating as we had determined that a much greater number of professional players are born earlier in the year, more than likely as a result of the global youth development structure."
